Sine Wave Equation: A Sine Wave Equation is graphically represented as shown in Fig. 4.10(a). The amplitude of a sine wave is represented on vertical axis. The angular measurement (in degrees or radians) is represented…
Simpson Theory of Lightning: The factors that contribute to the formation or accumulation of charge in the clouds are too many and uncertain. But during thunderstorms, positive and negative charges become separated by the heavy…
Simple Testing Station: In these Testing Station the short-circuit power is supplied by specially designed short-circuit generators, driven by induction motors. A simplified diagram of such a testing station is shown in Fig. (18.1). The…
Simple Slope Detector - Circuit diagram and its Characteristics: The circuit diagram of a simple slope detector is depicted in Fig. 22.52(a). This Slope Detector circuit consists of a tuned circuit which is slightly detuned…
Simple Diode Detector: Operation of diode detector: The Simple Diode Detector is by far the most common device used for AM demodulation (or detection), and its operation will now be considered in detail. On the…
Simple Cylindrical Cavity Wavemeter: Resonant cavities find extensive use as wavemeter at microwave frequencies. They enjoy high accuracy, mechanical simplicity, and a large physical size in proportion to the wavelength being measured. Practical cavity wavemeter…
Simple Biasing Circuit Diagram: The simplest biasing circuit diagram could be as shown in Fig. 12.4. The emitter-base junction is forward biased by the battery VBB and the collector-base junction is reverse biased by the…
Silicon Unilateral Switch: The Silicon Unilateral Switch (SUS), also known as a four layer diode and as a Schokley diode, can be treated as a low-current SCR without a gate terminal. Figure 19-30 shows the…
Silicon Controlled Switch (SCS) - Symbol, Operation, Advantages and Application: Silicon controlled switch (SCS), like the SCR, is a unilateral, four layer, three junction P-N-P-N silicon device with four electrodes namely cathode C, cathode gate…
Silicon Controlled Rectifier Principle Operation: Silicon Controlled Rectifier Principle Operation (SCR) consists of four layers of semiconductor material, alternately p-type and n-type as illustrated in Fig. 19-1(a). Because of its construction, the SCR is sometimes…
