ON ACHIEVING MICRO-dB RIPPLE POLYPHASE FILTERS WITH BINARY SCALED COEFFICIENTS
İzzet Kale, Artur Krukowski, Niall Murphy · 1994
This paper reports on the establishment of the coefficient bounds for half-band fixed-point polyphase filters, having all their zeroes on the unit circle. The paper also reports on the algebraic details of the established bounds, exposing pictorially the coefficient interactions and the corresponding polo-zero-patterns (pzp) for the 5 th and 7 th order cases. Potential applications as well as sample filters, designed through the use of these bounds are also reported. Half-band
