In frequency modulated wave

Options

  1. AFrequency varies with time
  2. BBoth frequency and amplitude vary with time
  3. CAmplitude varies with time
  4. DBoth frequency and amplitude are constant

Correct answer

A. Frequency varies with time

Step-by-step solution

In frequency modulated wave, only frequency varies with time, while the amplitude remains constant. This wave can be shown as It is used in FM broadcasting, telemetry and RADAR etc.
