QUESTION
Consider an FIR lowpass filter design with the following specifications: Passband =0-800 Hz Stopband = 1,200-4,000 Hz Passband ripple = 0.
Consider an FIR lowpass filter design with the following specifications: Passband =0-800 Hz
Stopband = 1,200-4,000 Hz
Passband ripple = 0.1 dB
Stopband attenuation = 40 dB
Sampling rate = 8,000 Hz
Determine the following:
a. window method
b. length of the FIR filter
c. cutoff frequency for the design equation
