A bandpass filter rejects direct current.

A. True

B. False

I had been asked this question in an online interview.

I would like to ask this question from Communication Systems in division Communication Systems of Physics – Class 12

The correct option is A. True

To elaborate: Yes, this is a true statement. A bandpass filter rejects low and high frequencies and allows a band of frequencies to pass through. So, when a signal is passed through a bandpass filter, it rejects dc and the sinusoids of frequencies ωm, 2ωm, and 2ωc and retains the frequencies ωc, ωc – ωm, and ωc + ωm.The output of the bandpass filter, therefore, is of the same form is hence an AM wave.
