High-fidelity finite-impulse-response filters with optimal stopbands
R.H. Wilkinson · IEE Proceedings G Circuits Devices and Systems · 1991
The paper describes a method of designing a high-fidelity lowpass finite-impulseresponse (FIR) filter having a maximally flat passband and an optimally contoured stopband in the Chebyshev sense. Certain other filters can be derived from it, including a lowpass filter with an equirippled passband and a maximally flat stopband.
