Electronics (Mike Jaroch)

A tubular raceway, usually metal or plastic, for holding wires or cables [4].

Scanning in which the movement of the beam describes a cone, the axis of
which coincides with that of the reflector [18].

Another term for DRIVEN ARRAY [10].

In radar, an object that reflects RF energy; target [18].

An uninterrupted, complete path for current flow [3] [16].

The on-off keying of a carrier [12].

A type of synchro that transmits angular information equal to the algebraic sum or difference of the electrical input supplied to its stator, the mechanical input supplied to its stator, and the mechanical input supplied to its rotor. The output is an electrical voltage taken from the rotor windings [15].

The electrode of a vacuum tube, other than a diode, upon which a signal voltage is impressed to regulate the plate current [6].

Synchro systems that contain control synchros and are used to control large amounts of power with a high degree of accuracy. The electrical outputs of these systems control servosystems, which in turn generate the required power to move heavy loads [15].

A group of components systematically organized to perform a specific control
purpose. These systems are categorized as either closed- or open-loop systems. The main difference between the two is that the closed-loop system contains some form of feedback [15].
