National Instruments Corporation
drivers software that controls a specific hardware device such as a DAQ board
or a GPIB interface board
DSP digital signal processing
dual-access memory memory that can be sequentially accessed by more than one controller
or processor but not simultaneously accessed. Also known as shared
memory.
dual-ported memory memory that can be simultaneously accessed by more than one
controller or processor
dynamic range the ratio of the largest signal level a circuit can handle to the smallest
signal level it can handle (usually taken to be the noise level), normally
expressed in dB
E
ECL emitter-coupled logic
EEPROM electrically erasable programmable read-only memory—ROM that can
be erased with an electrical signal and reprogrammed
EGA enhanced graphics adapter
EISA extended industry standard architecture
electrostatically coupled propagating a signal by means of a varying electric field
EMC electromechanical compliance
encoder a device that converts linear or rotary displacement into digital or pulse
signals. The most popular type of encoder is the optical encoder, which
uses a rotating disk with alternating opaque areas, a light source, and a
photodetector.
EPROM erasable programmable read-only memory—ROM that can be erased
(usually by ultraviolet light exposure) and reprogrammed
ETS equivalent-time sampling
event the condition or state of an analog or digital signal
expansion ROM an onboard EEPROM that may contain device-specific initialization
and system boot functionality
