Remez algorithm became a useful tool in the branches of science and engineering and was used for problems from di erent elds. One signi - cant application was employing the algorithm for the design of a lter rst introduced by Parks and McClellan [11]. Historically, minimax rational approximations were used to representing special

14.01.2022 · Remez Algorithm The Remez algorithm (Remez 1934), also called the Remez exchange algorithm, is an application of the Chebyshev alternation theorem that constructs the polynomial of best approximation to certain functions under a number of conditions.
