New design methods for FIR filters with equiripple stopbands and prescribed degrees of passband flatness
Palghat P. Vaidyanathan · 2005
A technique is presented for designing linear-phase digital FIR filters, with a prescribed degree of flatness in the passband, and a prescribed (equiripple) attenuation in the stopband. The design is based entirely on appropriate use of the McClellan-Parks algorithm along with certain maximally flat building blocks.
