Software with a graphical user interface containing the feature set of an
ASTRO radio.
See digital-to-analog conversion.
See digital-to-analog converter.
Data terminal equipment; for example, a computer.
A pre-defined set of parameters.
Refers to data that is stored or transmitted as a sequence of discrete
symbols from a finite set; most commonly this means binary data
represented using electronic or electromagnetic signals. See also
analog.
Conversion of a digital signal to a voltage that is proportional to the input
value. See also A/D.
A device that converts digital data into analog signals. See also ADC.
A type of digital communication that utilizes privacy call, as well as
memory channel and busy channel lock-out to enhance communication
efficiency.
A microcontroller specifically designed for performing the mathematics
involved in manipulating analog information, such as sound, that has
been converted into a digital form. DSP also implies the use of a data
compression technique.
Object code executed by the Digital Signal Processor in an ASTRO
subscriber radio. The DSP is responsible for computation-intensive
tasks, such as decoding ASTRO signaling.
See Digital Private-Line. See also PL.
See digital signal processor.
See digital signal processor code.
See Data terminal equipment.
Electrically Programmable Digital Potentiometer.
See Electrically Erasable Programmable Read-Only Memory.
A special type of PROM that can be erased by exposing it to an
electrical charge. An EEPROM retains its contents even when the
power is turned off.
