VIA. A plated-thru hole in a printed wiring board. A via may exist between one or more adjacent board layers, or through the entire board. A blind via runs vertically between the top [or bottom] side and through one or more adjacent board layers, but not through the entire board. A buried via runs between one or more adjacent internal layers, but does not run to the top or bottom layer. [PWB Design]
VIDEO AMPLIFIER. An amplifier designed to amplify the entire band of frequencies from 10 hertz (10Hz) to 6 megahertz (6 MHz). Also called a WIDE-BAND AMPLIFIER.
VIDEO ENHANCEMENT FEATURES. See ANTIJAMMING CIRCUITS.
VINCULUM. A straight horizontal line placed over one or more members of a compound logic expression to negate or complement. Also, used to join two or more members together.
VIRTUAL GROUND. A point in a circuit that is at ground potential (0 V) but is not connected to ground.
VOLT. The unit of electromotive force or electrical pressure. One volt is the pressure required to send 1 ampere of current through a resistance of 1 ohm.
VOLTAGE. The term used to signify electrical pressure. Voltage is a force that causes current to flow through an electrical conductor. The voltage of a circuit is the greatest effective difference of potential between any two conductors of the circuit.
VOLTAGE AMPLIFIER. An amplifier in which the output-signal voltage is greater than the input-signal voltage.
VOLTAGE-DIODE DETECTOR. A series-diode detector in which the diode is in series with the input voltage and the load impedance.
VOLTAGE DIVIDER. A series network in which desired portions of the source voltage may be tapped off for use in the circuit.
VOLTAGE DROP. The difference in voltage between two points. It is the result of the loss of electrical pressure as a current flows through a resistance.
VOLTAGE-FEED METHOD. Same as END-FEED METHOD.
VOLTAGE GAIN. The ratio of output voltage to input voltage in an amplifier.
VOLTAGE MULTIPLIERS. Methods of increasing voltages; used primarily where low current is required.
VOLTAGE REGULATION. A measure of the ability of a generator or power supply to maintain a constant output voltage from no-load to full-load operation. Expressed as a percentage of full-load voltage; the better the regulation, the lower the percent. [IC Voltage Regulators]
VOLTAGE STANDING WAVE RATIO (VSWR). In a waveguide, the ratio of the electric field (voltage) at a maximum point to that of an adjacent minimum point.
VOLTAIC CELL. A combination of materials used to convert chemical energy into electrical energy. A voltaic or chemical cell consists of two electrodes made of different types of metals or metallic compounds placed in an electrolyte solution
VOLTMETER. A meter used to measure voltage. [Equipment Manufacturers]
