Modulation and demodulation are two key processes used in data transmission, particularly in telecommunications.

1. Modulation: This is the process of converting or encoding the original information-bearing signal into a form suitable for transmission. It involves varying a carrier signal in order to use that signal to convey information. The three key parameters of a sine wave that can be modulated are its amplitude, frequency, and phase. Therefore, we have Amplitude Modulation (AM), Frequency Modulation (FM), and Phase Modulation (PM).

2. Demodulation: This is the reverse process of modulation. It involves extracting the original information-bearing signal from the carrier so that it can be processed at the receiver end. The demodulator takes the modulated carrier signal and regenerates the original information signal for use by the receiver device.

In summary, modulation is used to send a signal over a long distance, while demodulation is used to receive the sent signal at the receiver end.
