摘要	The object of the present invention is to provide an improved convolution processor that requires no multiplica tion operations and can easily be implemented digitally. The convolution processor comprises a first delta analog to digital converter (3) disposed in a first path (1) for one of first (f(t)) and second (g(t)) input waveforms being operated on to provide a convolution function to convert signals in the first path to a digital version thereof having a delta modulation format; a second delta analog to digital converter (4) disposed in a second path (2) for the other of the first and second input waveforms to convert signals in this second path to a digital version thereof having the delta modulation format; a sum mer (5) coupled to the output of the first and second paths and a pair of integrators (6, 7) coupled in any of the following manner in the above circuit; namely, in the first path, in the second path, in the first and second paths, in the output of the summer, in the first path and the output of the summer, and in the second path and the output of the summer. The convolu tion function is provieded at the output of the summer when the pair of integrators is coupled in the first path, the second path and in the first and second paths while the convolution function output is provided at the output of at least one of the pair of integrators when the pair of integrators is coupled in the output of the summer, in the first path and the output of the summer and, in the second path and the output of the summer.
