The AND gate in this circuit is functioning as a modulator in this circuit. The corresponding demodulator is built into the receiver. Identify another everyday system where modulator/demodulators pairs or used.

Modems are everyday devices in which modulators and demodulators are used.
The word "modem" reflects a contraction in the expression modulator-demodulator. A modem is usually used for wireless data transmission over a phone line. The transmitting modem modulates the data in a telephone-compatible signal and transfers the signal through the receiving modem back to digital data. Digital data transfers to and from radio signal from cellular modems.
In order to convert digital signals to analogue and vice versa, modems are intended. The difference between demodulation and modulation. Modulation is the method of influencing the carrier's data information, while demodulation is the retrieval of the original information from the carrier at the distant end. The unit that performs both modulation and demodulation is the modem. The modem translates the analogue signal on the telephone line into the computer's digital signal. The method of transforming an analogue signal into a digital signal is modulation, and modulator does this operation.
