Chapter 6

Windowing

Abstract

This chapter throws light on the windowing, aiming to optimize finite impulse response (FIR) filter frequency response with a finite number of coefficients. The chapter explains the process of truncating of infinite number of coefficients through windowing that generate a desirable response. This is further elaborated through tapering of coefficients, which holds importance for designers to manage passband and stopband ripple with a trade-off of increasing the transition band. Lastly, with some relevant examples of coefficient windows, aspect of Windowing is supported in all FIR-related filter design software programs.
