The Parks–McClellan algorithm, published by James McClellan and Thomas Parks in 1972, is an iterative algorithm for finding the optimal Chebyshev finite impulse response (FIR) filter. The Parks–McClellan algorithm is utilized to design and implement efficient and optimal FIR filters. It uses an indirect … See more In the 1960s, researchers within the field of analog filter design were using the Chebyshev approximation for filter design. During this time, it was well known that the best filters contain an equiripple characteristic in … See more In August 1970, James McClellan entered graduate school at Rice University with a concentration in mathematical models of analog filter design and enrolled in a new course called "Digital Filters" due to his interest in filter design. The course was taught jointly by … See more Before applying the Chebyshev approximation, a set of steps were necessary: 1. Define … See more The following additional links provide information on the Parks–McClellan Algorithm, as well as on other research and papers written by James McClellan and Thomas Parks: 1. Chebyshev Approximation for Nonrecursive Digital Filters with Linear Phase See more The Parks–McClellan Algorithm is implemented using the following steps: 1. Initialization: Choose an extremal set of frequences {ωi }. See more The picture above on the right displays the various extremal frequencies for the plot shown.
