A convolution is an integral that expresses the amount of overlap of one function as it is shifted over another function.

It therefore “blends” one function with another. For example, in synthesis imaging, the measured dirty map is a convolution of the “true” CLEAN map with the dirty beam the Fourier transform of the sampling distribution.

The convolution is sometimes also known by its German name, faltung “folding”.

Convolution is implemented in the Wolfram Language as Convolve [ fgxy ] and DiscreteConvolve [ fgnihtegral ]. Abstractly, a convolution is defined as a product of convoluclon and that are objects in the algebra of Schwartz functions in. Convolution of two functions and over a finite range is given by. The animations above graphically illustrate the convolution of two boxcar functions left and two Gaussians right.

In the plots, the green curve shows the convolution of the blue and red curves as a function ofthe position indicated by the vertical green line. The gray region indicates the product as a function ofso its area as a function of is precisely the convolution. One feature to emphasize and which is not conveyed by these illustrations since they both exclusively involve symmetric functions is that the function must be mirrored before lagging it across and integrating.

The convolution of two boxcar functions and has the particularly simple form. Even more amazingly, the convolution of two Gaussians.

Let, and be arbitrary functions and a constant. Convolution satisfies the properties. The area under a convolution is the product of areas under the factors. There is also a definition of the convolution which arises in probability theory and is given by.

Domenico Carlo Maria Dragonetti 7 April — 16 April was rragonetti Italian double bass virtuoso and composer with a 3 string double bass. By that time he had become notable throughout Europe and had turned down several opportunities, including offers from the Tsar of Russia. Inhe finally moved rnodo London to play in the orchestra of the King’s Theatreand settled there for the remainder of his life. In fifty years, he became a prominent figure in the musical events of the English capital, performing at the concerts of the Philharmonic Society of London as eondo as in more private events, where he would meet the most influential persons in the country, like the Prince Consort and the Duke of Leinster.

He andantf acquainted with composers Joseph Haydn and Ludwig van Beethovenwhom he visited on several occasions in Viennaand to whom he showed ronxo possibilities of the double bass as a solo instrument. His ability on the instrument also demonstrated the relevance of writing scores for the double bass in the orchestra separate from that of the cellowhich was the common rule at the time.

He is also remembered today for the Dragonetti bowwhich he evolved throughout his life. He began playing the guitar and the double bass by himself on his father’s instruments. He was soon noticed by Doretti, a violinist draognetti composer of ball music, who took him along for public performance in Venice. At the age of twelve, he was placed under the tuition of Berini, the best master for the double bass in Venice, who decided after only eleven lessons that he could not teach the boy anything more.

At the age of thirteen, Dragonetti was appointed principal player at the Opera Buffa in Venice. At fourteen he was appointed principal double bass player in the Grand Opera Seria at the San Benedetto theatre. When dragonteti eighteen, in Trevisohe was invited to join the quartet of the Tommasini, and was noticed by Morosiniprocurator of San Marcowho indulged dragonettti in auditioning for the admission in the Chapel of San Marco.

He made a first attempt inwhich was lost to Antonio Spinelli. He finally joined the institution on 13 September as the last of the five double bass players of the Chapel with a yearly income of 25 ducats.

He soon became the principal bassist. He later was offered a place by the Tsar of Russia, which was declined and got him a salary raise in the Chapel. He became very famous at the time, started playing andabte pieces, which was exceptional at the time for the double bass, and even got elected as of the directors of a musical festival held for the coming of fourteen sovereign princes to the republic of Venice.

Dragonnetti of his concertos was particularly remarked by the queen of Naples. He was offered another position to the Tsar of Russia, which he declined after the procurators of St Mark increased his salary to an exceptional 50 ducats.

They even granted him a leave for a year, with a continuation in his wages, to go to the King’s Theatre in London. That leave was extended for three more years afterwards, but finally Dragonetti never returned to Venice for more than a brief period during the French occupation of the city, Dragonetti had no close family, but had many close friends in the musical world in London. The story that he kept and often traveled with a collection of life-sized cloth mannequins, bringing them to his concerts and having them placed in front row seats of theaters, and even introducing one of these dolls as his wife, is completely unsubstantiated.

He was an avid collector, and did indeed collect dolls, sometimes taking one along on trips to amuse the children, of whom he was very fond. He never did learn to speak English, expressing himself in a mixture of Italian, English, French and Venetian dialect, but dragonrtti an astute businessman, and in fact, helped his surviving family rondl Venice financially.

THOMAS MARTIN says:

The authoritative source for information on him is the book of Dr. Fiona Palmer, Domenico Dragonetti in England — pub. He left Venice on 16 Septemberpartly under the influence of his friend, Giovanni Battista Cimador who composed a concerto for double bassand participated in the first rehearsals at the King’s Theatre, on 20 October and finally appeared as orchestra member in the opera Zenobia in Palmiraby Giovanni Paisielloon 20 December After only a few months, he became very famous in London, and his brilliant career was to last till the end.

Later he became intimate with the Prince Consort and the Duke of Leinster. He took part between andin forty-six concerts held by the Philharmonic Society of London. At the Italian Opera orchestra, he met the cellist Robert Lindleywho became his close friend and with whom he shared the stand during fifty-two years. They made a specialty at playing Arcangelo Corelli ‘s sonatas. At the age of 82, Dragonetti visited Bonn in August to participate in the 3-day music festival held as part of the inauguration of the Beethoven Monument there.

He died in his Leicester square lodgings at the age of 83 and was buried on 23 April in the vaults of the Roman Catholic chapel of St Mary, Moorfields. In his remains were moved to the Roman Catholic cemetery at Wembley.

InJoseph Haydn accepted a lucrative offer from German impresario Johann Peter Salomon to visit England and conduct new symphonies with large orchestras. The visit was dtagonetti huge success and generated some of his best known work. Another trip was therefore scheduled in On that second occasion, Haydn met Dragonetti, who became a very good friend, and who visited him in Vienna in On that first trip to Vienna, Dragonetti also met Beethoven in a famous encounter.

Dragonetti was not more remarkable for his astounding execution than dragonetti the deep, genuine musical feeling which elevated and ennobled it.

He was now – in the spring ofso far as the means are at hand of determining the time – returning to London from a visit to his native city, Venice, and his route took him to Vienna, where he remained several weeks. Beethoven and he soon met and they were mutually pleased with each other. Many years afterwards Dragonetti related the following anecdote to Samuel Appleby, Esq.

Beethoven played his part, with his eyes immovably fixed draggonetti his companion, and, in the finale, where the arpeggios occur, was so delighted and excited that at the close he sprang up and threw his arms around both player and instrument”.

The unlucky contrabassists of orchestras had frequent occasions during the next few years to know that this new revelation drabonetti the powers and possibilities of their instrument to Beethoven was not forgotten.

To this day, the mastering of the Beethoven double bass symphonic parts are considered a basic standard for all orchestral double bass players. Dragonetti came back to Vienna for an extensive stay in On that second trip he became friends with composer Simon Sechterwho would become the court organist inand professor of composition at the Vienna Conservatorium in He wrote piano dargonetti to some of his concert pieces, and they maintained a lifelong correspondence.

Dragonetti was again in Vienna in and got to meet once more Beethoven, who had just written Wellington’s Victoryto celebrate the victory of Wellington over the French armies of King Joseph Bonaparte at the Battle of Vitoria.

The premiere of this work, as well as of Beethoven’s seventh symphony was performed on 8 December in the University’s Festsaal, with Dragonetti leading the double basses. Dragonetti was known for his formidable strength and stamina. It was particularly important at a time when the role of the double bass in the orchestra was to assist the concertmaster in maintaining the cohesion and establishing the tempo. He had huge hands with strong, broad fingers, which allowed him to play with a taller bridge and strings twice as far from the fingerboard as the other bassists.

The physical quality is his huge hand: A hand endowed with five fingers so long, big and agile, that all five, including the bent thumb, go up and down the fingerboard each playing a note. This was not at all standard in these times, as most players used to play – in one position – one note with the index finger, and one with the other three fingers in combination.

Dragonetti was a lover of the fine arts, and a collector of musical instruments as well as many art-related articles, such as original scores and paintings. When he died, the following instruments were dispatched: Mention is made of this on The Contrabass Shoppe web site which says Palmer Clarendon Press Oxford seems to offer the most plausible account.

Because of Dragonetti’s unprecedented virtuosity as a soloist, attractive offers of work were made from both London and Moscow. As remuneration for renouncing the offers and remaining as principal bassist with the orchestra of the Ducal Chapel of St Mark’s in Venice an orchestra of considerable importancea decree made in gave Dragonetti a financial gratuity. Similarly, it is reputed that Dragonetti was presented with an instrument made by Gasparo da Salo — by the Benedictine nuns who occupied St Peter’s monastery in Vicenza where Dragonetti lived and played in the Grand Opera.

In the Palmer biography, a footnote refers to a account by C.

When amdante left for Rodo inDragonetti left many papers and manuscripts, including a Complete system of the double bass, or instruction book for that instrumentcontaining many elaborate exercises and studies, in the care of a friend. Unfortunately, they were sold and could not be retrieved by their author when he returned to Venice after some years.

Today, many of his letters, personal papers, compositions, solos and manuscripts are to be found in the British Library. Some were directly bequeathed by Dragonetti, some were offered by Vincent Novelloand some were bought at auctions.
