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
