Digital input/output channel signal.
Direct memory access—A method by which data can be transferred
to/from computer memory from/to a device or memory on the bus while the
processor does something else. DMA is the fastest method of transferring
data to/from computer memory.
Differential nonlinearity—A measure in LSB of the worst-case deviation of
code widths from their ideal value of 1 LSB.
Digital output.
Electrically erasable programmable read-only memory—ROM that can be
erased with an electrical signal and reprogrammed.
Field-Programmable Gate Array.
A configuration that is downloaded to the FPGA and that determines the
functionality of the hardware.
An unwanted signal excursion of short duration that is usually unavoidable.
Hour.
Hardware-in-the-loop.
Hertz.
