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 travel far …

In amplitude modulation the information signal varies the amplitude of the carrier wave, a process that produces a band of frequencies known as sidebands on each side of the carrier frequency.

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 …

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 …

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 …

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 the …

Oct 16, 2025 · Immunomodulators modulate the immune system to help your body respond to a disease or illness. Learn about the different types, uses, effectiveness, and more.

Aug 20, 2024 · The modulator combines the audio and video signals and assigns them a specific RF channel frequency. This RF signal is then sent to the TV, which can tune into the corresponding …
