Given below are two statements:
Statement I : A speech signal of $2kHz$ is used to modulate a carrier signal of $1MHz$ . The bandwidth requirement for the signal is $4kHz$ .
Statement II : The side band frequencies are $1002kHz$ and $998kHz$ . In the light of the above statements, choose the correct answer from the options given below:

Question

Given below are two statements:

Statement I : A speech signal of $2kHz$ is used to modulate a carrier signal of $1MHz$ . The bandwidth requirement for the signal is $4kHz$ .

Statement II : The side band frequencies are $1002kHz$ and $998kHz$ . In the light of the above statements, choose the correct answer from the options given below:

Quantrex Academy · Accepted Answer

Correct answer: B. Both Statement I and Statement II are true

f _ m = 2kHz f _ c = 1MHz = 1000kHz Band width = 2 f _ m = 4kHz ∴ Side frequencies will be = f _ c ± f _ m = (1000 ± 2)kHz = 998kHz and 1002kHz So, statement-I & statement-II both are correct.
