Glossary of Terms
Noise Reduction - A process by which the level of extraneous noise or
hiss in a signal is reduced considerably. The Samson UHF Synth
system utilizes the dbx® system of noise reduction.
Receiver - A component that receives a modulated radio signal and
restores the original audible signal by utilizing demodulation.
RF - Short for “Radio Frequency.”
Transmitter - A component that transmits an audible signal by causing
it to modulate a high-frequency inaudible carrier signal.
True Diversity - A wireless reception system by which a single chassis
houses two discrete receivers, with both tuned to the same frequency
but with each using an independent antenna. A built-in computer chip
then continuously scans the two receivers and determines which one
has the clearest and strongest reception, automatically (and silently)
switching to that channel.
UHF (Ultra High Frequency) - Refers to radio waves in the 300 - 3,000
megaHertz range.
VHF (Very High Frequency) - Refers to radio waves in the 30 - 300
megaHertz range.
VU - Short for “Voltage Unit.” A unit of measurement utilized by audio
devices that denotes relative signal strength. 0 VU is generally taken to
indicate unity gain (no boost or attenuation).
Wave - Refers to the transference of energy in a regular, back-and-forth
vibration.
Wavecycle - One single backwards-and-forwards motion of a wave.
