An additional oscillator used in a receiver when it is receiving a
cw signal. It provides an audible tone [17].


The unit that expresses the logarithmic ratio between the input and output of any given component, circuit, or system [16].


The ratio of a change in collector current to a corresponding change in base current when the collector voltage is constant in a common-emitter circuit [7].


A horizontal, long-wire antenna designed for reception and transmission of
low-frequency, vertically polarized ground waves [10].


Difference of potential applied to a vacuum tube or transistor to establish a reference operating level [13].


Current that flows through the base-emitter junction of a transistor and is adjusted to set the operating point of the transistor [13].


An array that radiates in opposite directions along the line of maximum
radiation [10].


(1) A number system that uses a base, or radix, of 2. Two digits (1 and 0) are used in the binary system. (2) Pertaining to a characteristic that involves the selection, choice, or condition in which there are only two possibilities. (3) A bistable multivibrator (flip-flop) is one example of a binary device [13].


A method of representing two possible conditions (on or off, high or low, one or zero, the presence of a signal or absence of a signal). Electronic circuits designed to work in such a way that only two conditions are possible [13].


(1) A character that represents one of the two digits in the number system that has a radix of two. (2) Either of the digits 0 or 1 that may be used to represent the binary conditions of on or off [13].
