Figure 15-4:
Frequency response of a typical equiripple, linear-phase FIR filter.
The filter used for the frequency response is a 37-tap filter used twice to achieve 96
dB attenuation in the stop bands. The response is calculated for a sample frequency
of 10 Hz, the roll-off start frequency is 3.33 kHz, and the noise floor begins at 6.667
kHz.
