Question

Where is modulation done?

• A. Radio Receiver
• B. Transmitter
• C. Between Radio Receiver and Transmitter
• D. None of the above

Answer 1

The correct option is B

Transmitter

1. The modulation acts as a signal cloak for the carrier signal. Modulation is the process of combining an input signal with a carrier signal to change the carrier wave's characteristics while masking the original message signal. Modulation can take on a variety of forms.
2. The name of the technique, amplitude modulation, refers to how the signal's height is changed. The input signal's frequency is altered during frequency modulation. Phase modulation involves modifying the signal's phase. These modulation techniques are applied.
3. In contrast to frequency modulation, which modifies the input signal's frequency, amplitude modulation alters the height of the signal. During phase modulation, signal phase is changed. The modulation strategies look like this. The communication system needs modulation.
