Design And Performance Analysis Of IIR Filter For RF Applications
This paper presents design and simulation of IIR bandpass filter for RF applications. Three different techniques
are used for design simulation namely Butterworth, Chebyshev and elliptic. The design has been analyzed and compared in
terms of transition width and group delay. The hardware requirements are also computed in terms of multipliers and adders.
It can be observed from the simulated result that the magnitude response and group delay of Butterworth and Chebyshev
type 1 are almost same at higher order and better than Chebyshev type 2 and elliptic filter. Multiplier requirement of
Chebyshev type 1 filter is 45% less than Chebyshev type 2 and elliptic filter and adder requirement of Butterworth and
Chebyshev type 1 is 25% less than Chebyshev type 2 and elliptic filter.
