Question

In amplitude modulation, the modulation index m, is kept less than or equal to 1 because

• A. m > 1, will result in interference between carrier frequency and message frequency, resulting into distortion
• B. m > 1 will result in overlapping of both side bands resulting into loss of information
• C. m > 1 will result in phase between carrier signal and message signal
• D. m > 1 indicates amplitude of carrier signal is greater than amplitude of message signal resulting into distortion

Answer 1

Answer: (B), (D)

The correct options are
B m > 1 will result in overlapping of both side bands resulting into loss of information
D m > 1 indicates amplitude of carrier signal is greater than amplitude of message signal resulting into distortion
