In AM, why is the modulation index kept less than or equal to 1 ? |
m > 1, will result in interference between carrier frequency and message frequency, resulting into distortion m > 1, will result in overlapping of both side bands resulting into loss of information m > 1, will result in change in phase between carrier signal and message signal m > 1, indicates amplitude of message signal greater than the amplitude of carrier signal resulting into distortion |
m > 1, will result in overlapping of both side bands resulting into loss of information |
If m > 1, the frequency deviation will be greater than the maximum frequency of the modulating wave which will result in overlapping of the side bands. |
