F.M., A.M. and S.S.B. transmitters

Explanation of question 23

Distortion can occur in J3E transmission if

  1. i and ii are both true
  2. i is true but ii is false
  3. i is false but ii is true
  4. i and ii are both false

The answer is :- 1 J3E transmission is single sideband, suppressed carrier telephony. Class C amplifiers are not linear and therefore not used (use AB or B). Overdriving a linear amplifier will produce distortion and harmonics.
