Identify the 'INCORRECT' statement from the following.

Options

  1. AModulation index is kept greater than one to avoid distortion.
  2. BThe receiving antenna is followed by amplifier, intermediate frequency (IF) stage and detector.
  3. CAM detection is carried out using a rectifier and an envelop detector.
  4. DModulated signal is to be followed by power amplifier and then fed to an antenna.

Correct answer

A. Modulation index is kept greater than one to avoid distortion.
