Glossary
SWR
Standing-Wave Ratio; on a transmission line, the
ratio of the maximum voltage to the minimum
voltage or maximum current to the minimum
current; also the ratio of load impedance to
intended (50 ohms) load impedance.
THD
Total Harmonic Distortion
translator
A transmitter designed to internally change an
FM signal from one frequency to another for
retransmission. Used in conjunction with terres-
trial-fed networks.
satellator
A transmitter equipped with an FSK ID option for
rebroadcasting a satellite-fed signal.
UHF
Ultra High Frequency; frequencies in the 300 to
3000 MHz range.
VCO
Voltage-Controlled Oscillator
VHF
Very High Frequency; frequencies in the 30 to
300 MHz range.
VSWR
Voltage Standing-Wave Ratio; see "SWR."
Wideband
See "broadband."
