Appendix A. Glossary
A.1 Terms
AC
See
VAC
(Appendix p. 12).
A/D
Analog-to-digital conversion. The process that translates analog voltage
levels to digital values.
accuracy
A measure of the correctness of a measurement. See also
Accuracy,
Precision, and Resolution
(Appendix p. 13).
Amperes (Amps)
Base unit for electric current. Used to quantify the capacity of a power
source or the requirements of a power consuming device.
analog
Data presented as continuously variable electrical signals.
ASCII / ANSI
Abbreviation for American Standard Code for Information Interchange /
American National Standards Institute. An encoding scheme in which
numbers from 0-127 (ASCII) or 0-255 (ANSI) are used to represent pre-
defined alphanumeric characters. Each number is usually stored and
transmitted as 8 binary digits (8 bits), resulting in 1 byte of storage per
character of text.
asynchronous
The transmission of data between a transmitting and a receiving device
occurs as a series of zeros and ones. For the data to be "read" correctly, the
receiving device must begin reading at the proper point in the series. In
asynchronous communication, this coordination is accomplished by having
each character surrounded by one or more start and stop bits which
designate the beginning and ending points of the information (see
Synchronous
(Appendix p. 11)).
baud rate
The speed of transmission of information across a serial interface,
expressed in units of bits per second. For example, 9600 baud refers to bits
being transmitted (or received) from one piece of equipment to another at a
rate of 9600 bits per second. Thus, a 7 bit ASCII character plus parity bit
plus 1 stop bit (total 9 bits) would be transmitted in 9/9600 sec. = .94 ms or
about 1000 characters/sec. When communicating via a serial interface, the
