Glossary-2

codeplug

Firmware that contains the unique personality for a system or device. A
codeplug is programmable and allows changes to system and unit
parameters. See also firmware.

coder/decoder

A device that encodes or decodes a signal.

CPS

See Customer Programming Software.

CTS

See clear to send.

Customer
Programming
Software

Software with a graphical user interface containing the feature set of a
radio. See also RSS.

D/A

See digital-to-analog conversion.

DAC

See digital-to-analog converter.

debounce time

An amount of time (which is set using a hardware device or software)
that ensures that only a single signal will be acted upon for a single
opening or closing of a contact.

deemphasis

In an FM transmission, the process of restoring the amplitude-versus-
frequency characteristics of the signal.

default

A pre-defined set of parameters.

deviation

The difference, usually the absolute difference, between a number and
the mean of a set of numbers, or between a forecast value and the
actual value.

digital

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.

digital-to-analog
conversion

Conversion of a digital signal to a voltage that is proportional to the input
value. See also A/D.

digital-to-analog
converter

A device that converts digital data into analog signals. See also ADC.

digital signal
processor

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.

digital signal
processor code

Object code executed by the Digital Signal Processor in a subscriber
radio. The DSP is responsible for computation-intensive tasks, such as
decoding ASTRO signaling.

DSP

See digital signal processor.
