NOTE 2: The filter gain outside of the passband is measured with respect to the gain at 1024 Hz. The analog input test signal is a sine wave with
0 dB = 4 VI(PP) as the reference level for the analog input signal. The pass band is 0 to 3600 Hz for an 8-kHz sample rate. This pass
band scales linearly with the sample rate.
