Audio Frequency; the frequencies between 20 Hz
and 20 kHz in the electromagnetic spectrum.
Automatic Level Control
Amplitude Modulation; the process of impressing
information on a radio-frequency signal by varying
its amplitude.
The range of frequencies available for signalling.
Binary-Coded Decimal; a digital system that uses
binary codes to represent decimal digits.
Beat Frequency Oscillator
A bayonet locking connector for miniature coax;
said to be short for Bayonet-Neill-Concelman.
As used in the FM transmitter, refers to the entire
audio spectrum as opposed to the spectrum influ-
enced by the pre-emphasis; also called "Wideband."
A continuous signal which is modulated with a
second, information-carrying signal.
In FM broadcasting, this term generally refers to
the interaction between the main (L+R) and the
subcarrier (L–R) signals as opposed to "separation"
which generally refers to leakage between left (L)
and right (R) channels.
A high average of modulation over time.
The amount by which the carrier frequency
changes either side of the center frequency.
Dual In-line Pins; term used to describe a pin
arrangement.
The unwanted changes in signal wave shape that
occur during transmission between two points.
Digital Panel Meter
Erasable Programmable Read Only Memory
(1) A circuit that supplies the initial oscillator used
in the driver stage. (2) A transmitter configuration
which excludes stereo generation and audio
processing.
