] ABSTRACT OF THE DISCLOSURE An inverse control system is disclosed, which comprises FIR filters provided between transmitting elements at n (n = 2, 3, ...) input points of a linear FIR system and a common signal source, for an inverse control such as to provide desired impulse responses between the signal source and m (n > m) output points of the linear FIR system. A j-th (j = 1, 2, ..., n) one of the FIR filters has a number Lj of taps which satisfies the relationships represented by Image for all i = 1, 2, ..., m and j = 1, 2, ..., n where wij is the number of discrete signals representing the impulse response gij(k) between the j-th output point and i-output point and Pi is the number of discrete signals representing the desired impulse response ri(k) between the signal source and i-th output point. The j-th FIR filters has a filter coefficient hj(k) satisfying the relationship Image for all i = 1, 2, ..., m where ? is a discrete convolution.
