Band Stop FIR Filter with the Fourier Series and the Dolph Chebyshev Window.

Cuthbert Nyack
This applet illustrates the effect of the Dolph-Chebyshev window on the frequency and impulse response of a band stop filter derived from the Fourier Series.

Image below shows a band stop filter with a stop band attenuation of 100dB.
