Given, below are two statements
Statement I A speech signal of

2\mathrm{ }kHz

is used to modulate a carrier signal of

1MHz.

The bandwidth requirement for the signal is

4\mathrm{ }kHz

.
Statement II The side band frequencies are

1002\mathrm{ }kHz

and

998\mathrm{ k}Hz

. In the light of the above statements, choose the correct answer from the options given below

View answer and explanation

Correct option: C

Both Statement I and Statement II are true.

Option C (Both Statement I and Statement II are true) is correct because the bandwidth requirement for AM is twice the modulating signal frequency, and the sideband frequencies are the sum and difference of carrier and modulating frequencies.
