mux multiplexer—a switching device with multiple inputs that sequentially
connects each of its inputs to its output, typically athigh speeds, in
order to measure several signals with a single analog input channel
mV millivolts
N
NC not connected

noise an undesirable electrical signal—Noise comes from external sources
such as the AC power line, motors, generators, transformers,
fluorescent lights, CRT displays, computers, electrical storms, welders,
radio transmitters, and internal sources such as semiconductors,
resistors, and capacitors. Noise corrupts signals you are trying to send
or receive.
O
OUT output pin—a counter output pin where the counter can generate
various TTL pulse waveforms
P
PCI Peripheral Componen t Interconnect—a high-performance expansion
bus architecture originally developed by Intel to replace ISA and EISA.
It is achieving widespread acceptance as a standard for PCs and
work-stations; it offers a theoretical maximum transfer rate of
132 MB/s.
