DESIGN OF IIR CHEBYSHEV LPF
AIM
Write a program in C and MATLAB to design IIR CHEBYSHEV low pass filter for the given specifications pass band frequency, stop band frequency, gain at pass band frequency and gain at stop band frequency. Verify the same on TMS 320 C 6713DSP kit, MATLAB.
TOOLS REQUIRED :
TMS 320C 6713 Kit,
Full version CCS s/w,
DSK 6713 s/w,
MATLAB s/w.
THEORY
The filters designed by considering all the infinite samples of impulse response are called IIR filters. It is a discrete time system that is designed to pass the spectral contents of the input signal in a specified band of frequencies. There are so many approximation solutions to design digital filters, among them popular approximations
3. BUTTERWORTH approximation
4. CHEBYSHEV approximation
