As can be seen from the list, the choice of required filter will
tend to define the set of permissible sample rates required.
The filter combination is set using the bandpass command,
which takes the tap number (0-2) and bandwidth factor (1, 2 or
5) as arguments. For example:
2 5 bandpass
defines the narrowest filter on the output from tap #2, the 20
samples/sec tap in our example, corresponding to a filter with
corners at 5.0Hz (50% Nyquist) and 9.0Hz (90% Nyquist). The
system response to the above command would be:
Tap#2 20 s/s Bandpass: 5.0->9.0Hz
