Instrumentation Laboratory Exercise 54
6.2 Circuit setup
The configuration above is set up as a high- pass filter. V
flt
will be fed
into pin 1 of the DAQ board, and circuit ground will be fed into the
ground (pin 39) of the DAQ. For the low- pass filter R
3
replaces C
1
,
which is moved between V
flt
and ground (as shown below).
Low- pass filter configuration. Component values are the same as
above.
