The linear convolution of anN-point vector,x, and anL-point vector,y, has lengthN+L- 1. For the circular convolution ofxandyto be equivalent, you must pad the vectors with zeros to length at leastN+L- 1 before you take the DFT. After you invert the product of the DFTs, retain onl...

As an aside, circular buffering is also useful in off-line processing. Consider a program where both the input and the output signals are completely contained in memory. Circular buffering isn't needed for a convolution calculation, because every sample can be immediately accessed. However, many ...
That is, , where the action of on the incident field will in general be in the form of a convolution. As is simply the mathematical description of T, inherits the symmetries of T. Thus, because of the cylindrical and mirror symmetries of the target and given an incident field , the ...
Circular convolution with the overlap–add method: When sequence x[n] is periodic, and Nx is the period, then y[n] is also periodic, with the same period. To compute one period of y[n], Algorithm 1 can first be used to convolve h[n] with just one period of x[n]. In th...
