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

May 14, 2024 · What is modulation? In order to understand what a modulator is, you have to understand what it does. A modulator, well, modulates. When you look at an unaltered video and audio signal, it …

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.

The device which performs modulation operation is called a modulator, and the resulting waveform or output of the modulator is called the modulated signal. The device which performs the inverse of …

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 travel far …

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 create …

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 properties of the …
