Frequency Modulation (FM)
FM is a form of analog angle modulation in which the baseband information carrying signal varies the frequency of a carrier wave. Audio signals transmitted by FM radio are the most common. However, FM radio can also tra...
A Brief Introduction to RDS (Radio Data System for VHF/FM broadcasting)
The use of more and more frequencies for radio programmes in the VHF/FM range make it inceasingly difficult to tune a conventional radio to a desired programme. This kind of...
This allows you to play the music from your CD changer through your FM radio.
...FM radio works the same way that AM radio works. The difference is in how the carrier wave is modulated, or altered. With AM radio, the amplitude, or overall strength, of the signal is varied to incorporate the sound information. With FM, the frequenc...
To the shipboard radio operators, it was a miracle — a Christmas miracle. Instead of hearing the usual dots and dashes of Morse Code, these listeners heard an eerie Silent Night, played by a violin. It was Christmas Eve, 1906, and this broadcast...
Short for phase-locked loop, an electronic circuit that controls an oscillator so that it maintains a constant phase angle (i.e., lock) on the frequency of an input, or reference, signal. A PLL ensures that a communication signal is locked on a specif...
Also see modulation and frequency-shift keying (FSK).
Frequency modulation (FM) is a method of impressing data onto an alternating-current (AC) wave by varying the instantaneous frequency of the wave. This scheme can be used with analog or digit...
PFC (power factor correction; also known as power factor controller) is a feature included in some computer and other power supply boxes that reduces the amount of reactive power generated by a computer. Reactive power operates at right angles to true...
