CRYSTAL MICROPHONEA microphone that uses the piezoelectric effect of crystalline matter to generate a voltage from sound waves [12]. |
CRYSTAL OVENA closed oven maintained at a constant temperature in which a crystal and its holder are enclosed to reduce frequency drift [9]. |
CURRENTThe movement of electrons past a reference point. The passage of electrons through a conductor. Measured in amperes [1]. |
CURRENT RATINGThe safe current-carrying capacity of a wire or cable on a continuous basis [4]. |
CURRENT REGULATORA circuit that provides a constant current output [7]. |
CURRENT STANDING-WAVE RATIO (ISWR)The ratio of maximum to minimum current along a transmission line [10]. |
CURRENT-FEED METHODSame as CENTER-FEED METHOD [10]. |
CUSPSSharp phase reversals [12]. |
CUTOFFThe condition in a tube or transistor whereby the reverse bias prevents current flow [13]. |
CUTOFF FREQUENCYThe frequency at which the attenuation of a waveguide increases sharply and below which a traveling wave in a given mode cannot be maintained. A frequency with a half-wavelength that is greater than the wide dimension of a waveguide [11]. |
