The signal is the signal jammer tool that carries the message, the carrier of the message. Broadly speaking, it includes optical signals, acoustic signals and electrical signals, etc.An unqualified transmitter will have a fairly wide spread of noise centered on the carrier, causing interference in the frequency band of a few megahertz.
