Choose the correct statement for amplitude modulation
Choose the correct statement for amplitude modulation
Options
- AAmplitude of modulating signal is varied in accordance with the information signal.
- BAmplitude of modulated signal is varied in accordance with the information signal.
- CAmplitude of carrier signal is varied in accordance with the information signal.
- DAmplitude of modulated signal is varied in accordance with the modulating signal.
Correct answer
C. Amplitude of carrier signal is varied in accordance with the information signal.
Step-by-step solution
Amplitude modulation (AM) is a modulation technique used in electronic communication, most commonly for transmitting messages with a radio wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is varied in proportion to that of the information signal.
