PEC电气工程专业英语证书考试-Glossary and Definitions of Basic Electrical and electronics Terms Electronics is the branch of science that deals with the study of flow and control of electrons (electricity) and the study of their behavior and effects in vacuums, gases, and semiconductors, and with devices using such electrons. This control of electrons is accomplished by devices that resist, carry, select, steer, switch, store, manipulate, and exploit the electron. Here are the Most Commonly Terms and definitions used in Electronics and Electronics Engineering: A (amp)- Ampere AC/DC-Alternating current or direct current ADC -Analog-to-digital converter AFT -Automatic fine tuning AFC -Automatic flow controller, used in controlling the flow of gasses under pressure into a vacuum system AGC-Automatic gain control AM/FM -Amplitude modulation or Frequency modulation AMM -Analog multimeter antilog - Antilogarithm Ap -Power gain Apc-Automatic phase control Av -Voltage gain AVC -Automatic volume control AWG -American wire gauge AC- Alternating current A/D-Analog to digital AF-Audio frequency AFC -Automatic frequency control Ah -Ampere hour AM-Amplitude modulation Ai -Current gain c -Centi (10-2) C -Capacitance or capacitor CAD -Computer aided design CAM -Computer aided manufacture CATV -Cable TV CB -Common base configuration CB- Citizens band CC -Common collector CE-Common emitter cm –Centimeter cmil -Circular mil CPU- Central processing unit C (Q)-Coulomb CR cr -Junction diode CRO- Cathode ray Oscilloscope CRT -Cathode ray tube CT -Total capacitance cw -Continuous transmission E DC- or Erms Difference in potential e -Instantaneous difference in potential ECG- Electrocardiogram ECL -Emitter coupled logic EHF- Extremely high frequency EHV- Extra high voltage ELF- Extremely low frequency EMF-Electromotive for
