Performance Analysis Of Low Pass Fir Filter With Variation Of Zero Value Coefficients
In this paper the frequency response of FIR Low Pass Filter has been analyzed with respect to number of zeroes in
impulse response. The developed design has been simulated for five different zero valued coefficients configurations. It can
be observed from the design analysis that decreased number of zeroes results in degraded stop-band attenuation with
improvement in transition width. It is also observed that increased number of zeroes results in improved stop-band
attenuation but degrade transition width. The design with 20 zero valued coefficients shows an improvement of 73.75% stop-
band attenuation and degradation of 84.90% in transition width. The proposed design, with 12 zero coefficients, provides an
improvement of 40.6% in stop-band attenuation and 60% improvement in transition width.
