Determination of optimum coefficients of IIR Digital Butterworth Band-Stop Filter
Journal Title: International Journal of Advanced Research in Computer Engineering & Technology(IJARCET) - Year 2013, Vol 2, Issue 2
Abstract
Infinite Impulse Response(IIR) filter is of recursive type i.e. the present output sample depends on the present input samples, past input samples and past output samples. There are a number of methods available for the determination of filter coefficients. This paper is based on the analog to digital mapping technique to determine the IIR digital filter coefficient along with the computer simulation in Matlab 7 on the basis of the proposed algorithm. The result of the simulation is found to be satisfying.
