FIR Filter Design Techniques

Introduction FIR filters are filters having a transfer function of a polynomial in z- and is an all-zero filter in the sense that the zeroes in the z-plane determine the frequency response magnitude characteristic The z transform of a N-point FIR filter is given by N 1 H(z) = h ( n ) z n 0

What are the techniques used by MATLAB for FIR filter design?
Some of the techniques used by Matlab for FIR filter design are as follows: Three different functions i.e. fir1,fir2 and kaiserord [Mat02] are used to design FIR filters. Fir1 function implements the classical method of windowed linear-phase FIR digital filter design.
How do you design an IIR filter?
As in the case of FIR filters, the notation for an IIR filter is often simplified as shown in Figure 6.34. A popular method for IIR filter design is to first design the analog-equivalent filter and then mathematically transform the transfer function H(s) into the z-domain, H(z). Multiple pole designs are implemented using cascaded biquad sections.
What optimization techniques are involved in FIR filter design?
Different optimization techniques involved in FIR filter design are also covered, including Rabiner’s method for FIR filter design. These optimization techniques reduce the error caused by frequency sampling technique at the non-sampled frequency points.
