08.01.2021 · Design an IIR Bandpass Chebyshev Type-2 Filter using Scipy – Python Last Updated : 10 Nov, 2021 IR stands for Infinite Impulse Response, It is one of the striking features of many linear-time invariant systems that are distinguished by having an impulse response h(t)/h(n) which does not become zero after some point but instead continues infinitely.

Figure 2.1: Pafnuty Lvovich Chebyshev [Wikimedia Commons]. 2.2 Chebyshev’s interest in approximation theory Chebyshev was since his childhood interested in mechanisms. The theory of mechanisms played in that time an important role, because of the industri-alisation. In 1852, he went to Belgium, France, England and Germany to talk with
