Question
[Q1](A) The gain of a second order band-pass active filter at its upper cutoff frequency is 42
dB. The lower cutoff frequency is 10.8 KHz and Q-factor is 50. Assume that the center
frequency fo, which is equal to 15.3 KHZ, is midway between the cutoff frequencies.
Determine
1- The gain at center frequency.
2- The upper cutoff frequency.
3- The bandwidth.
(B) Design the filter with the specifications given in part (A) with equal values using Bessel
approximation technique. Choose C-0.01 nF and draw the complete circuit diagram for the
designed filter.
