Designing of digital FIR-filters with independently controlled phase-frequency characteristic

Abstract

The structural realization of digital FIR-filters using frequency sampling with real time control of phase-frequency characteristic is considered. The characteristics of elementary digital filters, the algorithm of their output signals summation and the way of phase-frequency characteristic shift are given.
