Silicon Bilateral Switch: It might be convenient to think of a Silicon Bilateral Switch (SBS) as an SUS with a gate terminal, or as a low-current TRIAC. However, the SBS is not simply another four-layer device.…
Signed Binary Numbers (Definition, Conversions & Examples): In the decimal number system, a plus (+) sign is used for denoting a positive number and a minus (-) sign for denoting a negative number. The plus…
Signal Flow Graph of DC Motor in Electric Drive System: The Signal Flow Graph of DC Motor in Electric Drive System block diagram representation discussed above is adequate only for simple systems having components with…
Signal Definition and Classification of Signals: A signal is a single valued function of one or more variables that conveys some information. Signals are represented mathematically as the functions of one or more independent variables.…
Signal Conditioning System: Signal Conditioning System - The measurand, which is basically a physical quantity, is detected by the first stage of the instrumentation or measurement system. The first stage is the detector transducer stage.…
Signal Conditioning of Inputs: Since all the data that have to be acquired, do not generally originate from identical sources, signal conditioning becomes necessary in some cases. A simple attenuator, is used to scale down…
SI Unit of Electrical Resistance: SI Unit of Electrical Resistance - When a current flows in a material, the free electrons move through the material and collide with other atoms. These collisions cause the electrons…
Shunted Armature Speed Control: Shunted Armature Speed Control - It is a variation of rheostatic control. As is obvious from Fig. 7.59, the principle used in achieving control is that of voltage division. In the…
Shunt Voltage Regulator Block Diagram: A shunt voltage regulator provides regulation by shunting current away from the load. The block diagram of such a voltage regulator is depicted in Fig. 43.12. The input unregulated voltage…
Shunt Clipping Circuits: A positive Shunt Clipping Circuits is illustrated in Fig. 3-28(a). Here the diode is connected in shunt (or parallel) with the output terminals. When the input is negative, the diode is reverse…
