differential nonlinearity—a measure in least significant bit of the
worst-case deviation of code widths from their ideal value of 1 LSB
performing frequency division on an internal signal
software that controls a specific hardware device such as a DAQ board or
a GPIB interface board
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 decibels
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.
the condition or state of an analog or digital signal
an onboard EEPROM that may contain device-specific initialization and
system boot functionality
external digital trigger
a voltage pulse from an external source that triggers an event such as A/D
conversion
