V

VERY LOW FREQUENCY

The band of frequencies from 3 kilohertz to 30 kilohertz [17].

VIDEO AMPLIFIER

An amplifier designed to amplify the entire band of frequencies from 10 hertz (10 Hz) to 6 megahertz (6 MHz). Also called a WIDE-BAND AMPLIFIER [8].

VIDEO ENHANCEMENT FEATURES

See ANTIJAMMING CIRCUITS [18].

VINCULA

Plural of vinculum (see below) [13].

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 [13].

VIRTUAL GROUND

A point in a circuit that is at ground potential (0 V) but is not connected to ground [8].

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 [1].

VOLTAGE

(1) The term used to signify electrical pressure. Voltage is a force that causes current to flow through an electrical conductor. (2) The voltage of a circuit is the greatest effective difference of potential between any two conductors of the circuit [1].

VOLTAGE AMPLIFIER

An amplifier in which the output-signal voltage is greater than the input-signal
voltage [8].

VOLTAGE DIVIDER

A series network in which desired portions of the source voltage may be tapped
off for use in the circuit [1].
