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 the fractional value of nsmaller in bilinear transform?
- 2=k 1) log( s= p) = 2:4546 Note that although we still need to have 3 poles, the actual fractional value of Nsmaller because of the greater ratio of stopband to passband edge frequencies provided by the nonlinear frequency warping of the bilinear transform.
What are the advantages of bilinear Z transform?
- There are several advantages in using the bilinear z- transform. Firstly, the equiripple amplitude properties of the filters are preserved when the frequency axis is compressed. Secondly, there is no aliasing of the original analogue frequency response. As a result, the response of a low-pass filter falls to zero at ? = ?.
