Assuming sampling rate at 48kHz, design an order-40 low-pass filter having cut-off frequency 10kHz bywindowing method. In your design, use Hamming window as the windowing function.
b = fir1(40,10.0/48.0) Assuming sampling rate at 48kHz, design an order-40 lowpass filter having transition band 10kHz-11kHzusing the Parks-McClellan optimal FIR filter design algorithm.
b = remez(40,[1 1 0 0],[0 10/48 11/48 1])
