Answer :- 12)a) The first opamp circuit is a high pass filter. This is cascaded with other op-amp circuit which is a low pass filter. Thus the overall circuit is a Band Pass Filter.
The cut-off frequency of HPF is-
The cut-off frequency of LPF is-
So the filter allows to pass the signal from 318.3 Hz to 397.88 Hz. Other frequency signals are stopped.
Answer :- 12)b)i) The bandwidth is-
Answer :- 12)b)ii) The center frequency is-
Answer :- 12)b)iii) The quality factor is-
