(a) m > 1, will result in interference between the carrier frequency and message frequency, resulting in distortion
(b) m > 1 will result in overlapping of both sidebands resulting into loss of information
(c) m > 1 will result in a change in phase between the carrier signal and the message signal
(d) m > 1 indicates the amplitude of message signal greater than the amplitude of the carrier signal resulting in distortion
Answer:
The correct options are:
(b) m > 1 will result in overlapping of both sidebands resulting into loss of information
(d) m > 1 indicates the amplitude of message signal greater than the amplitude of the carrier signal resulting in distortion
Explanation:
We know that the modulation index is given by the expression;
If then . This means that both side bands of the modulated wave will overlap, resulting in information loss.
