21. Refer to the Band Pass Filter Design
Utility. The following parameters can be
used.
Note : The Wizard does not currently
work properly. Cypress plans on
having it fixed in a future release.
22. The following parameters for the
Programmable Gain Amplifier should be
used.
• For secondary testing, the gain
can be varied here and
experimented
Notes :
• This is prior to the filter, so only
setting gains <1 should have
an effect. Another option would
be to change the gain in the
Filter.
• You can have PGA <1 (like
suggested above) and then
change the gain of the BPF
itself to see the effect on
amplitude.
• The gain on the BPF is
negative (not obvious with a
sine wave output).
