Pin unblocking key.
Type of pulse modulation in which a code is used to represent quantized values
of instantaneous samples of the signal wave.
Activates the transmitter so that a message can be sent. This operation is
performed by pressing and holding the PTT key while sending the message.
Quadrature amplitude modulation.
Portion of the frequency spectrum between audio sound and infrared light
(10 Hz - 10 GHz).
Device that amplifies RF signals. This device separates the audio signal from
the RF carrier, amplifies it, and converts it back to the original sound waves.
Combination of electric and magnetic fields with varying radio frequencies that
are capable of traveling through space at the speed of light.
Random access memory.
RISC control engine.
Control of a system whose functions are performed more than 100 ft. from the
base station. See also local control.
Radio station that automatically rebroadcasts received radio signals.
See radio frequency (RF).
Reduced instruction-set computer.
