Question:

In the transmission and receiving of amplitude modulation of a signal, following steps are required. Arrange these in correct sequence.

(A) Modulated signal is fed to an antenna after providing necessary power through power amplifier before transmission
(B) The signal is passed though a rectifier, followed by a envelope detector to receive the message signal
(C) The modulating signal is superimposed on high frequency carrier wave
(D) After receiving antenna the received signal is fed to amplifier and then passed through. If stage where carrier frequency is lowered

Choose the correct answer from the options given below:

Options:

(A), (B), (C), (D)

(B), (C), (D), (A)

(C), (B), (A), (D)

(C), (A), (D), (B)

Correct Answer:

(C), (A), (D), (B)

Explanation:

The correct answer is Option (4) → (C), (A), (D), (B)

Transmission and reception of amplitude modulated signal

Modulated signal is superimposed on high frequency carrier wave.

Thus the step are on : C → A → D → B
