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.
VSWR Voltage Standing-Wave Ratio; see "SWR."
Wideband See "broadband."
