The center frequency and Quality Factor for all of these
filters is the same. The values can be calculated in the
following manner:
(23)
Designing a band pass filter with a center frequency of 10
kHz and Quality Factor of 5.5
To do this, first consider the Quality Factor. It is best to pick
convenient values for the capacitors. C
= C
= 1000 pF.
Also, choose R
= R
= 30 k
. Now values of R
and R
6
need to be calculated. With the chosen values for the ca-
pacitors and resistors, Q reduces to:

f = 62.8 kHz.
Using the expressions above, the appropriate resistor values
will be R
