Abstract

The paper presents mathematical models of digital frequency-sampling filters with shiftable phase-frequency characteristic (PFC) and a generalized mathematical model taking into account the PFC shift introduced at the input. The conducted investigations made it possible to develop a class of narrow-band filters with the possibility of PFC shift and the real-time variation of instantaneous phase of the output signal.
