CHAPTER 5Finite Impulse Response (FIR) Filters

This chapter focuses on the workhorse of DSP: the finite infinite response (FIR) filter. We discuss three main topics. First, we talk about the structure of an FIR filter, how to build one, and some of its properties. Next, we show how, given the filter coefficients, to compute the frequency response of the filter (normally, this is done with software, but we can gain insight by understanding how to perform this procedure). Last, we show a method to compute coefficients to meet a given frequency response. This last step is what is commonly required of a DSP designer: to find the number and value of filter coefficients required for frequency response required by the application. Again, this procedure ...
