- AAmplification
- BDemodulation
- CTransmission
- Correct answerDModulation
Solution
The process of super imposing message signal on high frequency carrier wave is called modulation. It is usually applied
to electromagnetic signals. Common modulation methods are - amplitude modulation, frequency modulation, phase
modulation.
