EMC: (Electromagnetic Compatibility) That condition in which electrical/electronic systems can perform their intended function without experiencing degradation from, or causing degradation to other electrical/electronic systems.

EME: (Electromagnetic Environment) The total electromagnetic energy in the RF spectrum that exists at any given location.

EMI: (Electromagnetic Interference) Any [man-made or natural] induced, radiated, or conducted electrical emission, disturbance, or transient that causes undesirable responses, degradation in performance, or malfunctions of any electrical or electronic equipment, device, or system. Also see Radio Frequency Interference [RFI].

EMITTER: Any device or apparatus which emits electromagnetic energy. Also a terminal on a transistor.

EMP: [Electromagnetic Pulse] A very narrow high-amplitude pulse of electromagnetic noise.

Error Signal: In servo-mechanisms, the signal applied to the control circuit that indicates the degree of mis-alignment between the controlling and the controlled members. In tracking radar systems, a voltage dependent upon the signal received from a target whose polarity and magnitude depend on the angle between the target and the center axis of the scanning beam. [Error Terms].

Externally Synchronized Radar: A Radar system in which timing pulses are generated by a master oscillator external to the transmitter.
