Figure 16 : Multiple Feedback 8-pole Bandpass Filter
Figure 17 : Six pole 355Hz Low-pass Filter (chebychev type)
This is a - pole Chebychev type with ±0.25dB ripple in the passband. A decoupling stage is used to avoid
the influence of the input impedance on the filter’s characteristics. The attenuation is about 55dB at 710Hz
and reaches 80dB at 1065Hz. the in band attenuation is limited in practise to the ±0.25dB ripple and does
not exceed 0.5dB at 0.9fc.
