C
CARRIER-CONTROLLED APPROACHA shipboard radar system used to guide aircraft to safe landings in poor visibility conditions [18]. |
CARRY(1) One or more digits, produced in connection with an arithmetic operation, that is/are forwarded to another digit place for processing there. (2) The number represented by the digit or digits in (1) above [13]. |
CATCHER GRIDIn a velocity-modulated tube, a grid on which the spaced electron groups induce a signal. The output of the tube is taken from the catcher grid [11]. |
CATHODE(1) In an electron tube the electrode that is the source of current flow [6]. (2) The general name for any negative electrode [1]. (3) The negative terminal of a forward-biased semiconductor diode, which is the source of the electrons [7]. |
CATHODE BIASThe method of biasing a vacuum tube in which the biasing resistor is placed in the common-cathode return circuit, thereby making the cathode more positive with respect to ground [6]. |
CATHODE KEYINGA system in which the cathode circuit is interrupted so that neither grid current nor plate current can flow [12]. |
CATHODE MODULATORVoltage on the cathode is varied to produce the modulation envelope [12]. |
CATHODE SPUTTERINGA process of producing thin film components [14]. |
CATHODE-RAY TUBE (CRT)An electron tube that has an electron gun, a deflection system, and a screen. This tube is used to display visual electronic signals [6]. |
CAVITY RESONATORA space totally enclosed by a metallic conductor and supplied with energy in such a way that it becomes a source of electromagnetic oscillations. The size and shape of the enclosure determine the resonant frequency [11]. |
