Chapter 5
Finite Impulse Response (FIR) Filters
Abstract
This chapter explores the fundamentals of the finite infinite response filter, the workhorse of digital signal processing. It starts with the structure of finite impulse response (FIR) filter, the methods to build it, and the properties. The chapter shows how the number and value of the filter coefficients determine the frequency response of an filter. The characteristic of FIR filters is discussed in detail with emphasis so as to why it is preferred over other type of digital filters.
