Abstract :
The authors describe an exchange algorithm for the frequency domain design of linear-phase FIR equiripple filters where the Chebyshev error in each band is specified. The algorithm is a hybrid of the algorithm of Hofstetter, Oppenheim and Siegel and the Parks-McClellan algorithm. The authors also describe a modification of the Parks-McClellan algorithm where either the passband or the stopband ripple size is specified and the other is minimized
