摘要
Abstract
This paper presents a method of interpolation filter design with minimum Chebyshev error in approximating a desired ideal frequency response. Other than traditional ways of approximating ideal filter in time domain, this method, according to design requirement, comes up with a prototype of Equiripple Nyquist Filter, of which an Optimum Interpolation Filter(OIF)is proposed by time-domain interpolation and convolution. The prototype filter and time-domain interpolation filter endow OIF the ability to accurately control its frequency response under various circumstances. And the simulation results reveal that OIF provides not only the best performance among all kinds of filters with the same response time, but also the best Chebyshev approximation of ideal filter.关键词
