ABSTRACT:
A multipulse excitation signal, as a better approximation than a single-pulse excitation signal, searches for a kth pulse which minimizes either a difference between a synthesized and a reference signal, or a distance between a multipulse excitation signal and a residual signal. The search uses an averaging function M.sub.k (n) of a weighted error signal.
