Audio Frequency; the frequencies between 20 Hz
and 20 kHz in the electromagnetic spectrum.
Amplitude Modulation; the process of impressing
information on a radio-frequency signal by varying
its amplitude.
The range of frequencies available for signaling.
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
influenced by the pre-emphasis; also called
"Wideband".
In FM broadcasting, the 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.
The amount by which the carrier frequency changes
either side of the center frequency.
The unwanted changes in signal wave shape that
occur during transmission between two points.
(1) A circuit that supplies the initial oscillator used in
the driver stage.
(2) A transmitter configuration which excludes
stereo generation and audio processing.
Frequency Modulation; the process of impressing
a radio signal by varying its frequency.
Light Emitting Diode
The process by which a carrier is varied to
represent an information-carrying signal.
A transmission within a localized geographic area
(ranging from a single room to several kilometers).
A 19-kHz signal used for stereo transmissions.
The deliberate accentuation of the higher audio
frequencies; made possible by a high-pass filter.
