Cost Analysis Of Digital Fir Filter Using Different Window Techniques
In FIR filter implementation, numbers of multiplier and adder circuits play an important role in chip area, speed
and cost. In this paper, cost has been analyzed based on various windowing techniques. All window techniques have been
compared in terms of number of adders and multipliers. The filter has been designed and simulated using Matlab 7.6. Results
show that performance of Blackman & Hanning window techniques are better as compared to Rectangular,Hamming and
Bartlett. Performance has been further improved using Kaiser and Equiripple window methods. Equiripple window based
FIR filter has shown 28.97% reduction in multiplier and 29.08% in adder as compared to Kaiser to provide cost effective
solution for DSP applications.
