摘要：

In the paper a method for minimum-phase, sparse impulse response FIR filter design was presented. The proposed solution uses an interpolation filter and is dedicated for narrowband filters. It was demonstrated, that the number of non-zero coefficients of the filter designed by the proposed method is smaller than the number of coefficients obtained by other methods, with preserved magnitude frequency response of the filter.
