Abstract :
The Nyquist (1928) 1 filters (NFls) with both nonlinear phase response and amplitude response of nonspecified symmetry are investigated. It is shown that one of the filter´s responses (amplitude or phase) can be chosen almost arbitrary. The second one is then derived from the condition of zero intersymbol interference (ISI) in data transmission synchronous systems. As a specific application of the presented theory, a simple procedure for calculating NFl´s with ISI-free matched and unmatched filter properties is proposed
