Note:
Radio Frequency Interference (RFI): A high frequency, cyclic series of
spikes or noise injected onto an electrical line by means of radio wave energy or
by a piece of equipment connected to the line. Exists when either the
transmitter or receiver is carrier operated (has an antenna), causing undesired
responses to or from other electronic equipment or systems.
