A modulator is a device or circuit that performs modulation. A demodulator (sometimes detector) is a circuit that performs demodulation, the inverse of modulation.

A modulator is an electronic circuit that superimposes a low-frequency (information) signal onto a high-frequency (carrier) signal for the purpose of wireless transmission.

But what is a modulator? A modulator changes a signal so it can send information, like your voice or data, through a communication channel. This process, called modulation, helps signals …

Feb 10, 2025 · A modulator is an electronic device or circuit that modifies a carrier signal to encode information from a message signal. The modulator works by varying one or more …

Modulation is a fundamental technique in signal processing where one signal (the modulator) is used to systematically vary properties of another signal (the carrier). This process allows us to …

Jul 23, 2025 · The process by which data is converted into electrical/digital signals for transferring that signal over a medium is called modulation. It increases strength for maximum reach of the …

Oct 26, 2023 · In the broad world of electronics and telecommunications, the term ‘modulator’ has a significant importance. A modulator is a device that performs modulation, a process where …
