Abstract :
A method is presented to generate polynomials with phase values and delay (first derivative) specified at given frequencies. Developments are presented in the simultaneous low-pass approximation problem of amplitude, phase, and delay. The closed-form solutions (reciprocal and nonreciprocal) are expressed in terms of the arbitrary phase and delay polynomials (APD)
