What is IIR filter design?

IIR filter design primarily concentrates on the magnitude response of the filter and regards the phase response as secondary. The most common design method for digital IIR filters is based on designing an analogue IIR filter and then converting it to an equivalent digital filter.

What is the finite difference equation of an IIR filter?

The finite difference equation and transfer function of an IIR filter is described by Equation 3.3 and Equation 3.4 respectively. In general, the design of an IIR filter usually involves one or more strategically placed poles and zeros in the z-plane, to approximate a desired frequency response.

Can an infinite impulse response filter display pure linear-phase characteristics?

It is therefore referred to as an infinite impulse response (IIR) filter. Assuming the filter is causal, so that the impulse response h[n] = 0 for n < 0, it follows that h[n] cannot be symmetrical in form. Therefore, an IIR filter cannot display pure linear-phase characteristics like its adversary, the FIR filter.

What is an iir system?

An IIR ?lter is one class of linear time-invariant system. We can represent the function of the ?lter as a difference equation: y[n] = ? XN k=1 aky[n?k] + XM k=0
