In-class Exercise Designing a Low-Pass Op Amp Filter Using the circuit shown in Fig. 15.1, calculate values for
C
and
R_(2)
that, together with
R_(1)=1\Omega
, produce a low-pass filter having a gain of 1 in the passband and a cutoff frequency of
1ra(d)/(s)
. Construct the transfer function for this filter and use it to sketch a Bode magnitude plot of the filter's frequency response.
