What happens when the amplitude of the carrier signal is lower than the amplitude of the modulating signal?
The amplitude of modulating signal is kept less than the amplitude of carrier wave to avoid distortion.
What happens to the carrier amplitude in frequency modulation?
In frequency modulation, the carrier amplitude remains constant, but its frequency is changed in accordance with the modulating signal.
What would happen if a 1 kHz signal amplitude modulated a 1 kHz carrier signal?
Sidebands. It is possible to plot the frequency spectrum of an AM transmission using a spectrum analyser. If a 1 kHz sine wave tone is modulated onto a 1 MHz carrier, two sidebands will be produced 1 kHz above and 1 kHz below the 1 MHz carrier signal.
What happens when amplitude of modulating signal is higher than carrier signal?
When the amplitude of the modulating signal is greater than the amplitude of the carrier, distortion will occur. 5. What is the effect of distortion? Explanation: Distortion occurs when the modulating signal amplitude is greater than the amplitude of the carrier, causing incorrect information to be transmitted.
