V
V ANTENNAA bidirectional antenna, shaped like a V, which is widely used for communications [10]. |
VACUUM EVAPORATIONProcess of producing thin film components [14]. |
VALENCEThe measure of the extent to which an atom is able to combine directly with other atoms. It generally depends on the number and arrangement of the electrons in the outermost shell of the atom [1]. |
VALENCE SHELLThe electrons that form the outermost shell of an atom [1]. |
VARAbbreviation for volt-amperes reactive [2]. |
VARACTORA PN junction semiconductor, designed for microwave frequencies, in which the capacitance varies with the applied voltage [7] [11] [12]. |
VARACTOR FM MODULATORAn FM modulator that uses a voltage-variable capacitor (varactor) [12]. |
VARIABLEA representative symbol that can assume any of a given set of values [13]. |
VARIABLE ATTENUATORAn attenuator for reducing the strength of an ac signal either continuously or in steps, without causing signal distortion [11]. |
VARIABLE RESISTORA wire-wound or composition resistor, the value of which may be changed over a designed range [1]. |
