High quality filters are essential part of vocoders. By means of filter banks structures we can combine modern DSP algorithms with hardware realizations having many parallel identical devices. This paper proposes digital filter realization based on filter bank structure suitable for hardware realization.

Index Terms. filter banks, generalized K.N-convolution, eigen transform, fast number-theoretic transform, fast polynomial transform.
