  1. Convolution is a mathematical way of combining two signals to form a third signal. It is the single most important technique in Digital Signal Processing. Using the strategy of impulse decomposition, systems are described by a signal called the impulse response.
  2. convolution: [ kon″vo-lu´shun ] a tortuous irregularity or elevation caused by the infolding of a structure upon itself.
  3. Definition of convolution. 1: a form or shape that is folded in curved or tortuous windings the convolutions of the intestines. 2: one of the irregular ridges on the surface of the brain and .
  4. 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).
  5. N-D convolution, returned as a vector, a matrix, or a multidimensional array. If A and B have the same number of dimensions, the full convolution C = convn(A,B) has size size(A)+size(B) When one or both of A and B are of type single, then the output is of type single. Otherwise, convn converts inputs to type double and returns type double.
  6. Convolve Convolve [ f, g, x, y] gives the convolution with respect to x of the expressions f and g. Convolve [ f, g, { x1, x2, }, { y1, y2, .
  7. ‘The convolution method increases the precision, relative to estimation of the individual linewidths by simulation.’ ‘The convolution method was used to distinguish a cell from the background.’ ‘The fitting of a sum of exponentials convoluted to an instrument response to experimental data is traditionally done by iterative convolution.’.
  8. Jul 09,  · Convolution Theorem. Let and be arbitrary functions of time with Fourier transforms. Take. (1) (2) where denotes the inverse Fourier transform (where the transform pair is defined to have constants and). Then the convolution is.
