	The graphical filter design is explained for a Chebyshev band pass filter with a center frequency of 8 kHz and one octave bandwidth (5657 Hz) and a prototype order of 5. The order of the digital filter is 10. The transition width between pass band and stop band is 1 kHz. The attenuation in the stop band is more than 30 dB. The ripples extent from 0 dB to -3 dB (<nowiki>+</nowiki>3dB attenuation). The center frequency of 8 kHz is the geometrical mean of the upper pass frequency (11314 Hz) and the lower pass frequency (5657 Hz).
