Convolution is a ubiquitous process that serves to describe effects ranging from acoustic echoes to the blurring of photographic images. In optics and electrical engineering, many devices are ...
In addition to substantial benefits in modulation speed (for changing the vector inputs), an optical implementation of a matrix-vector multiplier allows the harnessing of wavelength division ...
This article presents two important DSP techniques, the overlap-add method, and FFT convolution. The overlap-add method is used to break long signals into smaller segments for easier processing. FFT ...
