EMC terminology:
(1) Equipment refers to any electrical, electronic or electromechanical device that works as an independent unit and performs a single function.
(2) System refers to "several equipment, subsystems, full-time personnel and technical combinations that can perform or guarantee work tasks".
(3) Electromagnetic environment is the sum of all electromagnetic phenomena existing in a given place“ "Given place" is "space", and "all electromagnetic phenomena" includes all "time" and all "spectrum".
