STEP-TRANSMISSION SYSTEM

A data transmission system that operates on direct current. It consists
of a step transmitter (rotary switch) and a step motor interconnected to transmit data (information) between remote locations [15].


STICKOFF VOLTAGE

A low voltage used in multispeed synchrosystems to prevent false synchronizations [15].


STOP

The last unit of a teletypewriter signal. It is always a mark [17].

STRANDED CONDUCTOR

A conductor composed of a group of wires. The wires in a stranded conductor are usually twisted together and not insulated from each other [4].


STRANDS

Fine metallic filaments twisted together to form a single wire [4].

STRATOSPHERE

Located between the troposphere and the ionosphere; it has little effect on radio waves [10].


STROBOSCOPE

An instrument that allows viewing of rotating or reciprocating objects by producing the optical effect of a slowing down or stopping motion [16].


STUB

Short section of a transmission line used to match the impedance of a transmission line to an antenna. Can also be used to produce desired phase relationships between connected elements of an antenna [10] [18].


SUBASSEMBLY

Consists of two or more parts that form a portion of an assembly or a unit [17].

SUBHARMONIC

An exact submultiple of the fundamental frequency. Even subharmonics are one-half, one-quarter, and so on. Odd subharmonics are one-third, one-fifth, and so on of the fundamental frequency [17].
