All kinds of EMC wave filters are useful in audio, r.f. and EMI programs to isolate selected portions of the frequency spectrum.
Custom designed wave filters are readily available in different impedance values and with different response slopes outside the pass or reject bands. The slope of response outside of the passband depends on the number of poles (circuit elements). Butterworth style filters are usually preferred since the ripple in the passband is negligible.
