O
OPAQUEThose substances that do not transmit (pass) any light rays; that is, the light rays are either absorbed or reflected [10]. |
OPEN CIRCUIT(1) The condition of an electrical circuit caused by the breaking of continuity of one or more conductors of the circuit; usually an undesired condition. (2) A circuit that does not provide a complete path for the flow of current [1]. |
OPEN-ENDED LINEA transmission fine that has a terminating impedance that is infinitely large [10]. |
OPERATIONAL AMPLIFIERAn amplifier designed to perform computing or transfer operations and that has the following characteristics: (1) very high gain, (2) very high input impedance, and (3) very low output impedance [8]. |
OPTICAL COUPLERA coupler composed of an LED and a photodiode and contained in a light- conducting medium. Suitable for frequencies in the low-megahertz range [7]. |
OPTIMUM WORKING FREQUENCYThe most practical operating frequency that can be used with the least amount of problems and is roughly 85 percent of the maximum usable frequency [10]. |
OPTOELECTRONIC DEVICESDevices that either produce or use light in their operation [7]. |
OR GATEA gate that performs the logic OR function. It produces an output 1 whenever any or all of its inputs is/are 1 [13]. |
ORDER-WIRE CIRCUITA circuit between operators used for operations control and coordination [17]. |
ORGANIZATIONAL-LEVEL MAINTENANCEResponsibility of the user organization [14]. |
