5. Use the formula in step 3 of Section 19.8 to obtain a value for the multiplier, D. In
this case:
797.11
400
=D
The result is D = 33.9
6. Step 4 of Section 19.8 requires that you convert D to the closest 8 bit binary
integer. The closest integer to 33.9 is 34, and the 8 bit binary representation is
00100010. D7 is the most significant bit (MSB), and D0 is the least significant bit
(LSB).
7. Complete the filter configuration by installing jumpers according to step 5 of
Section 19.8. To configure the filter board for the high-pass corner frequency f
hp
=
400 Hz
Install: W13,W14,W15,W17,W18, and W42
Remove: W12 and W16
8. Channel A of the filter board is now completely configured. Configure channel B
as required and then verify the filter settings as described in Test Filter Options,
Section 19.15.
