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.
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
How do you design a digital filter?
- Design a digital filter equivalent of a 2nd order Butterworth low-pass filter with a cut-off frequency fc = 100 Hz and a sampling frequency fs = 1000 samples/sec. Derive the finite difference equation and draw the realisation structure of the filter.
