Frequency Modulation (or FM) synthesis is a simple and powerful method for creating and controlling complex spectra, introduced by John Chowning of Stanford University around 1973. In its simplest ...

A radio wave of a specific frequency that is modulated or changed in some way in order to transmit data. The amplitude of the carrier wave can be increased—for example, to indicate a one or zero of ...

The transmission of a fixed frequency ... (modulated) to "carry" data. The frequency is measured in Hertz (cycles per second). For example, the 2.5 GHz (gigahertz) Wi-Fi band means that a radio ...

The difference is in how the carrier wave is modulated, or altered ... varied to incorporate the sound information. With FM, the frequency (the number of times each second that the current ...

After “some” RF design courses, he decided that he had learned enough to build his own frequency-modulated continuous wave radar system. From the level of detail on this project, we’d say ...

Amplitude modulation (AM) is also widely used to alter a carrier wave to transmit data. For example, in AM radio, the voltage (amplitude) of a carrier with a fixed center frequency (the station's ...

Notice, too, that the frequency of the incoming and outgoing signals are the same. Carrier Wave Generator The Wave Generator creates a high-frequency radio signal. The frequency of this signal is ...

But for a weekend project, [Vinod.S] took the ultrasonic transmitter and receiver from a distance-meter module and used amplitude modulation ... to the low 40 kHz carrier frequency, the sound ...
