RTP Real Time Protocol is an Internet protocol that supports the real-time
transmission of voice and data.
Rx Receiver.
S
satellite voter A channel group member that has delegated voting activity to a central
voter.
SAW filter Surface Acoustic Wave filter. A band pass filter that can be used to filter both
RF and IF frequencies. A SAW filter uses the piezoelectric effect to turn the
input signal into vibrations that are turned back into electrical signals in the
desired frequency range.
selectivity The ability of a radio receiver to select the wanted signal and reject
unwanted signals on adjacent channels (expressed as a ratio).
sensitivity The sensitivity of a radio receiver is the minimum input signal strength
required to provide a usable signal.
signaling profile A named set of configuration items related to signaling that can be applied
to any channel.
simplex Able to provide transmission and reception in only one direction at a time.
simulcast The simultaneous broadcast by more than one transmitter of the same signal
on the same frequency.
SINAD Signal plus Noise and Distortion is a measure of signal quality. It is the ratio
of (signal + noise + distortion) to (noise + distortion). A SINAD of 12 dB
corresponds to a signal-to-noise ratio of 4:1.
site 1. The base station equipment at a particular location. This includes power
supplies, transmitters, receivers, network interfaces and controllers.
2. The location of that equipment.
skew A measure used in centrally voted channel groups. If a voice stream arrives
at the central voter 20 ms later than the first voice stream from the same SU,
it is said to have a skew of 20 ms.
