MS
million samples
MSB

noise
an undesirable electrical signal—Noise comes from external sources
such as the AC power line, motors, generators, transformers,
fluorescent lights, soldering irons, 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.
