Low pass filters. The following graphs show the available set of low 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.
