STICKOFF VOLTAGEA low voltage used in multispeed synchrosystems to prevent false synchronizations [15]. | ||
STOPThe last unit of a teletypewriter signal. It is always a mark [17]. | ||
STRANDED CONDUCTORA conductor composed of a group of wires. The wires in a stranded conductor are usually twisted together and not insulated from each other [4]. | ||
STRANDSFine metallic filaments twisted together to form a single wire [4]. | ||
STRATOSPHERELocated between the troposphere and the ionosphere; it has little effect on radio waves [10]. | ||
STROBOSCOPEAn instrument that allows viewing of rotating or reciprocating objects by producing the optical effect of a slowing down or stopping motion [16]. | ||
STUBShort 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]. | ||
SUBASSEMBLYConsists of two or more parts that form a portion of an assembly or a unit [17]. | ||
SUBHARMONICAn 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]. | ||
