Frequency Modulation (FM) sounds simple at first, but understanding the electronics behind modulation and demodulation of an FM signal can be confusing.

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 ...

In Frequency Shift Keying the transmitted signal shifts between two different frequencies to represent binary data, like two different notes from a piano. This would technically be 2-FSK modulation.

IN the United States, frequency-modulation has been assigned the wave band 42-50 m.c and at these frequencies, simplification in design and reduction in size of transmitters are of particular ...

Ultrasonic calls by rats may represent affective expressions and serve communicative functions. The temporal patterning and frequency modulation of the long, 21-30 kHz ultrasonic calls were studied in ...

The team put an electro-optic modulation element into a lithium niobate comb microresonator, according to their journal article. A lithium niobate resonator was able to tune the bandwidth and ...
