digital lowpass filter using Kaiser and Hamming window

Could you design a digital lowpass filter using Kaiser and Hamming window methods with the following specifications:

- Passband edge frequency 𝜔𝑝 = 0.25𝜋

- Stopband edge frequency 𝜔𝑠 = 0.35𝜋

- Peak approximation error 𝛿 should be less than -50dB

Please implement the digital filter in MATLAB and plot and analyze the impulse response, magnitude response and phase response of the filters. Verify the performance of the digital filters by applying a signal. If you can help I will be very pleased.

Yes, I could.

If you want to design one as well, use the fir1 functon. I also recommend the See Also section of the documentation.
