Abstract
Analog filters are generally built using resistors, capacitors, inductors, and operational amplifiers. The impulse response of such filters begins when the impulse arrives and continues indefinitely. A filter with an impulse response of this type is known as an infinite impulse response (IIR) filter.
In this chapter, we discuss the filter types available to the engineer designing digital filters. Some digital filters are IIR filters, while others are finite impulse response (FIR) filters. An FIR filter is a filter whose impulse response is identically zero after a certain time.
