Poles and Zeros of Transfer Function: Poles and Zeros of Transfer Function defines that, in general, the network function N(s) may be written as where a0,a1,...a2 and b0,b1,...bm are the coefficients of the polynomials P(s) and Q(s);…
Phase Controlled Line Commutated Converters: In these Phase Controlled Line Commutated Converters, the commutation voltage, i.e. the voltage required to transfer current from one thyristor to the other, is provided by the supply lines to…
Filter Fundamentals in Network Analysis: Filter Fundamentals in Network Analysis - The complete study of behavior of any filter section needs calculations of its characteristic impedance (Z0), propagation constant (γ), attenuation constant (α) and phase…
Switching Systems in Digital Communication: If only two sites are to be connected, switching is not required. The two facilities are interconnected on a point-to-point basis. However, switching is likely to be required where three…
Single Machine Infinite Bus in Power System: Figure 12.14 is the circuit model of a Single Machine Infinite Bus in Power System through a line of reactance Xe. In this simple case From Eq. (12.29b)…
Zener Diodes Characteristics: When a Junction diode is reverse biased, normally only a very small reverse saturation current flows; IS on the reverse characteristic in Fig. 2-25(a). When the reverse voltage is sufficiently increased, the…
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.…
Tap Changing Auto Transformer: Fig. 15.6 shows diagrammatically Tap Changing Auto Transformer. Here, a mid-tapped auto-transformer or reactor is used. One of the lines is connected to its mid-tapping. One end, say a of this…
Polyphase AC Motors for Traction Drives: Polyphase AC Motors for Traction Drives - Advantages of ac motors over dc we already know. Because of negligible maintenance, ruggedness and higher power per unit weight or volume,…
Motorola 68000 Pins and Signals: Fig. 11.3 illustrates the Motorola 68000 Pins and Signals. Data Transfer Control and Address Lines: D0-D15 is the bi-directional 16-bit data bus. A1-A23Â is the output 24-bit address bus. The UDS…
