In amplitude modulation, the modulation index \( m \), is kept less than or equal to 1 because
\( \mathrm{P} \)
(a) \( m1 \), will result in interference between carrier frequency
W and message frequency, resulting into distortion.
(b) \( m1 \) will result in overlapping of both side bands resulting into loss of information.
(c) \( m1 \) will result in change in phase between carrier signal and message signal.
(d) \( m1 \) indicates amplitude of message signal greater than amplitude of carrier signal resulting into distortion.
