Electronics (Mike Jaroch)

A bidirectional antenna, shaped like a V, which is widely used for communications [10].

Process of producing thin film components [14].

The 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].

The electrons that form the outermost shell of an atom [1].

Abbreviation for volt-amperes reactive [2].

A PN junction semiconductor, designed for microwave frequencies, in which the capacitance varies with the applied voltage [7] [11] [12].

An FM modulator that uses a voltage-variable capacitor (varactor) [12].

A representative symbol that can assume any of a given set of values [13].

An attenuator for reducing the strength of an ac signal either continuously
or in steps, without causing signal distortion [11].

A wire-wound or composition resistor, the value of which may be changed over
a designed range [1].

Same as REMOTE-CUTOFF TUBE [6].

Cotton cloth coated with insulation varnish. An insulation used on high-
voltage conductors [4].

A line used to represent both direction and magnitude [2] [12].

A diagram consisting of joined squares, which is used to give a graphic
representation of basic logic relations [13].

The rate at which a disturbance travels through a medium [10].

Modification of the velocity of an electron beam by the alternate acceleration and deceleration of electrons [11].

A servosystem which controls the speed of the load it is driving [15].

On a graph, the straight line axis that is plotted from bottom to top [10].

A pair of parallel electrodes in a CRT that moves the electron beam up and down [6].

The part of a radiation pattern that is radiated in the vertical plane [10].

An imaginary plane that is perpendicular to the horizontal plane [11] [18].

Waves that are radiated with the E field component perpendicular to the
earth's surface [10].

The band of frequencies from 30 megahertz to 300 megahertz [17].

An integrated circuit containing over 2,000 logic gates or 64,000 bits of memory [14].

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

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].

See ANTIJAMMING CIRCUITS [18].

Plural of vinculum (see below) [13].

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].

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

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].

(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].

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

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

The difference in voltage between two points. It is the result of the loss of electrical pressure as a current flows through a resistance [1] [4].

The ratio of output voltage to input voltage in an amplifier [6].

Methods of increasing voltages; used primarily where low current is required [7].

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 [5].

A series-diode detector in which the diode is in series with the input voltage and the load impedance [12].

Same as END-FEED METHOD [10].

A meter used to measure voltage [3] [16].

(VSWR)—In a waveguide, the ratio of the electric field (voltage) at a maximum point to that of an adjacent minimum point [10] [18].
