pilot A 19–kHz signal used for stereo transmissions.
pre-emphasis The deliberate accentuation of the higher audio
frequencies; made possible by a high-pass filter.
processing The procedure and/or circuits used to modify
incoming audio to make it suitable for transmis-
sion.
receiver An option which adds incoming RF capability to
an existing transmitter. See also "Translator."
RF Radio Frequency; (1) A specific portion of the
electromagnetic spectrum between audio-
frequency and the infrared portion. (2) A fre-
quency useful for radio transmission (roughly 10
kHz and 100,000 MHz).
SCA Subsidiary Communications Authorization; see
"subcarrier."
S/N Signal to Noise
spurious products Unintended signals present on the transmission
output terminal.
stability A tolerance or measure of how well a component,
circuit, or system maintains constant operating
conditions over a period of time.
stereo pilot See "pilot."
stereo separation The amount of left-channel information that
bleeds into the right channel (or vice versa).
subcarrier A carrier signal which operates at a lower fre-
quency than the main carrier frequency and
which modulates the main carrier.
suppression The process used to hold back or stop certain
frequencies.
