High Pass FIR Filter with the Fourier Series and the Kaiser Window.
This applet illustrates the effect of the Kaiser window on the frequency and impulse response of a high pass filter derived from the Fourier Series.
The image below show a high pass filter with a minimum stop band attenuation of
100dB for the variable Kaiser and 83dB for the standard Kaiser window.
The 0.1dB to 100dB transition bandwidth is ~ 0.046ws and the length is 103.
p to 3.19 gives similar charactreistics
for the standard Kaiser window but the stop band response is not as
