This simple IIR filter has a fixed frequency response and removes DC from the input signal.

In fact it is a highpass with a zero at 0Hz and a really fast slope. The step response (DC-signal with value 1) falls to almost 0 within about 600 samples. This is 13.6 ms @ 44.1 kHz.

In the Test ensemble it is used in a FM Feedback Loop.
