High pass filters. The following graphs show the available set of high pass filters. Their normalized frequency response is
shown from 0 to ½ the sample rate. These filters will operate at any sample rate with cutoff frequency scaled as shown below on
the graphs. The filters have normalized cutoff frequencies of 0.05, 0.1, 0.15, 0.20, 0.25, 0.3, 0.35, 0.40, and 0.45. Stop band
rejection is typically between –50 and –60 dB.
