Design a highpass FIR filter using Kaiser window design technique. The specifications are:
Stopband edge: 0.4pi;, As = 60dB
Passband edge: 0.6pi;, Rp = 0.5dB
Where As = Stopband attenuation in dB
And Rp = Passband ripple in dB
Plot the magnitude response (in dB) and the impulse response of the designed filter using MatLab.
The solution designs a highpass FIR filter using kaiser window.
