Electrical Definitions |
Scanner : A device that examines a spatial pattern one part after another and generates analogue or digital signals corresponding to the pattern.They are often used in mark sensing,pattern recognition or character recognition. |
Scintillation : A bunch of light obtained from certain materials when exposed to ionizing radiation. |
Semiconductor : A small component having an electrical conductivity between the high conductivity of metals and the low conductivity of insulators. |
Silicon Controlled Rectifier : It is three junction three terminal semiconductor diode used for switching moderate power devices. |
Sine Wave : A fundamental waveform whose amplitude varies as the sine of a linear function of its argument,expressed in either radians,degrees or time. |
Strain Gauge : A device that measures strain at the surface of a solid body means of changes in the electrical properties of associated circuits. |
Stray Capacitance : Capacitance which exists incidently between portions of a circuit at different potentials as opposed to capacitance intentionally placed in the circuit. |
Switching Time : The time from the 50% of level of command signal to the 90% of the RF output. |
