ERP

Enterprise Resource Planning ... software used by companies to track resources, orders, production, etc etc. Some of the better known software providers in this field are SAP and JD Edwards.

An ERP is an event-related potential. Really, it is a time-locked EEG record of activity related to a stimulus presentation or some cognitive event. ERPs are used by cognitive psychologists to determine what's going on in the brain during specific mental processing.

To record ERPs, EEG is recorded from the brain of a participant concurrently with the presentation of a stimulus. The records are averaged together, in the hopes that random electrical activity will average out, leaving only the activity related to the processing of the presented stimuli.

ERP also stands for Effective Radiated Power, which is:

(Peak Envelope Power _watts) * (Gain of antenna over a half-wave dipole)
