PACKAGING LEVELSA system developed to assist maintenance personnel in determining the repairability of components, printed circuit boards, modules, and so forth [14]. |
PAGE PRINTERA high-speed printer that prints teletypewriter characters one at a time in a full-page format [17]. |
PARABOLIC REFLECTORAn antenna reflector in the shape of a parabola. It converts spherical wavefronts from the radiating element into plane wavefronts [18]. |
PARALLAX ERRORThe error in meter readings that results when you look at a meter from some position other than directly in line with the pointer and meter face. A mirror mounted on the meter face aids in eliminating parallax error [3]. |
PARALLEL CIRCUITTwo or more electrical devices connected to the same pair of terminals so separate currents flow through each; electrons have more than one path to travel from the negative to the positive terminal [1]. |
PARALLEL LIMITERA resistor and diode, connected in series with the input signal, in which the output is taken across (parallel to) the diode [9]. |
PARALLEL-CONNECTED DUPLEXERConfiguration in which the tr spark gap is connected across the two legs of the transmission line one-quarter wavelength from the T-junction [18]. |
PARALLEL-NEGATIVE LIMITERA resistor and diode, connected in series with the input signal, in which the output is taken across the diode and the negative alternation is eliminated [9] |
PARALLEL-POSITIVE LIMITERA resistor and diode connected in series with the input signal, in which the output is taken across the diode and the positive alternation is eliminated [9]. |
PARALLEL-RESONANT CIRCUITA resonant circuit in which the source voltage is connected across a parallel circuit (formed by a capacitor and an inductor) to furnish a high impedance to the frequency at which the circuit is resonant. Often referred to as a tank circuit [9] [10]. |
