AIM:To write a program for IIR(Infinite Impulse Response) low pass filter using the window function using MATLAB in IT1254 - DSP and Communications Systems Lab.
ALGORITHM:Step 1: Start
Step 2: Read the pass band ripple
Step 3: Read the stop band ripple
Step 4: Read the pass band frequency
Step 5: Read the stop band frequency
Step 6: Read the sampling band frequency
Step 7: Perform low pass filter calculations
Step 8: Plot the output sequence
Step 9: Stop
rs=input('Enter the stopband ripple(rs):');
fp=input('Enter the passband frequency(fp):');
fs=input('Enter the stopband frequency(fs):');
f=input('Enter the sampling frequency(f):');
