Franklin Oscillator Circuit Diagram: A simple L-C oscillator, called the Franklin oscillator and its circuit diagram is shown in Fig. 21.12. Here two CE amplifier stages are employed to provide 360° phase shift from input to…
Decibels and Half Power Point Method: Power Measurement in Decibels and Half Power Point Method - The power gain (Ap) of an amplifier may be expressed in terms of the log of the ration of…
Node Elimination Technique in Power System: In stability studies, it has been indicated that the buses to be considered are those which are excited by the internal machine voltages (transient emf's) and not the load…
Op Amp Voltage Regulators: Voltage Follower Regulator - Refer once again to the Op Amp Voltage Regulators circuit in Fig. 17-11. The complete error amplifier has two input terminals at the bases of Q5 and…
Diesel Engine Power Plant - Layout, Types and Applications: Introduction: Diesel engine power plant (prime mover is a diesel engine) are installed where supply of coal and water is not available in sufficient quantity. These…
Normalized Low Pass Filter Characteristics: Normalized Low Pass Filter Characteristics - The passive filters are the filters consisting only passive components such as resistors, inductors, capacitors. These classical filters are designed starting with filter networks…
Phase Conversion in Transformer: Three Phase to Two Phase Conversion Transformer (Scott-T transformer or Scott Connection): Phase conversion from three to two phase is needed in special cases, such as in supplying 2-phase electric arc…
Principle of Induction Motor | Torque Slip Characteristic: Principle of Induction Motor has not been introduced so far. Consider a cylindrical rotor machine with both the stator and rotor wound for three phases and identical…
Transistor Construction: The transistor construction consists of a silicon or germanium (preferably silicon because of its smaller cutoff current ICBO, smaller variations in ICBOÂ due to variations in temperature and higher operating temperature) crystal in which…
Avalanche Photodiode - Definition, Basic Structure and Workings: The avalanche photodiode is similar to the P-N or PIN photodiode except that it is operated at high reverse-bias voltages so that impact ionization occurs, EHPs are…
