AI-4TUNING FORK—A two-pronged mechanical device that is designed to vibrate only at itsnatural frequency. In electronics, it is used primarily to determine the correct speed of amotor.UNIJUNCTION TRANSISTOR (UJT)—A three-terminal, semiconductor device with anegative-resistance characteristic that is used in switching circuits, oscillators, and wave-shaping circuits.VOLUME UNIT (VU)—Unit of measurement of a complex audio signal such as voice or music.A 0 level is referenced to 1 milliwatt of power into a 600-ohm load.WAVEMETERS—(1) Calibrated resonant circuits that are used to measure frequency. (2) Aninstrument for measuring the wavelength of an rf wave.ZENER DIODE—A pn-junction diode designed to operate in the reverse-bias breakdownregion.
