DECIMAL NUMERALA decimal representation of a number [13]. |
DECIMAL POINTThe radix point in decimal representation [13]. |
DECOUPLING CAPACITORA capacitor used to transfer unwanted signals out of a circuit; for example, coupling an unwanted signal to ground. Also called a BYPASS CAPACITOR [8]. |
DEFLECTION COILSIn a cathode-ray tube, coils used to bend an electron beam a desired amount [18]. |
DEFLECTION PLATESTwo pairs of parallel electrodes, one pair set forward of the other and at right angles to each other, parallel to the axis of the electron stream within an electrostatic cathode-ray tube [6]. |
DEGENERATIONThe process whereby a part of the output signal of an amplifying device is returned to its input circuit in such a manner that it tends to cancel part of the input [7]. |
DEGENERATIVE FEEDBACKFeedback in which the feedback signal is out of phase with the input signal; also called NEGATIVE FEEDBACK [8]. |
DEGREE-OF-FREEDOMThe number of axes about which a gyro is free to precess [15]. |
DEIONIZATION POTENTIALThe potential at which ionization of the gas within a gas-filled tube ceases and conduction stops; also referred to as extinction potential [6]. |
DEIONIZATION TIMEIn a spark gap, the time required for ionized gas to return to its neutral state after the spark is removed [18]. |
