LONG-WIRE ANTENNAAn antenna that is a wavelength or more long at its operating frequency [10]. |
LONGITUDINAL WAVESThose waves in which the disturbance (back and forth motion) takes place in the direction of propagation. Sometimes called compression waves [10]. |
LOOPA curved conductor that connects the ends of a coaxial cable or other transmission line and projects into a waveguide or resonant cavity for the purpose of injecting or extracting energy [10] [11]. |
LOOSE COUPLINGInefficient coupling of energy from one circuit to another that is desirable in some applications. Also called weak coupling [11]. |
LOW FREQUENCYThe band of frequencies from 30 kHz to 300 kHz [17]. |
LOW-LEVEL MODULATIONModulation produced in an earlier stage than the final [12]. |
LOW-NOISE AMPLIFIERSee PREAMPLIFIER [18]. |
LOW-PASS FILTERA filter that passes a majority of the low frequencies on to the next circuit and rejects, or attenuates, the higher frequencies. Also called a high-frequency discriminator [9] [12]. |
LOWER SIDEBANDAll difference frequencies below that of the carrier [12]. |
LOWER-FREQUENCY CUTOFFThe lowest frequency a circuit will pass [9]. |
