Infinite Impulse Response (IIR) Filters

The chapter opens with the discussion of infinite impulse response filters. The complex topic of IIR filter is more intricate than FIR filter and it probes deeper linking fundamental concepts of DSP. It leads to discussion of bilinear transform which specifies the filter response sand design of an analog filter using analog filter techniques. It also shows the mapping techniques in different domains and the responses from each domain and discusses the characteristics and method of frequency preparing techniques which prepares an analog filter and ends with the notes on how analog filter which itself is a complex subject converts into a digital IIR filter. It delves deeper into the subject matter to use the software programs which can help in designing and convert them into a digital IIR design.
