The details of low pass filter sections are given as fh =10kHz, AF= 2 and f=1.2kHz. Find the voltage gain magnitude of first order wide band-pass filter, if the voltage gain magnitude of high pass filter section is 8.32dB.

Question

Quizplus · Accepted Answer

The voltage gain magnitude of the band-pass filter is the sum of the voltage gain magnitudes of the low-pass and high-pass sections. The low-pass filter section has a gain of 2, which is 6.02 dB (20*log10(2)). Adding this to the high-pass filter gain of 8.32 dB gives a total of 14.34 dB, which is closest to 14.28 dB.
