Impulse Protective Gap Arrester: It was pointed out that the sphere gap has an impulse ratio of unity, but suffers from the drawback that the arc between its electrodes is not self-extinguishing. The horn gap…
Improving Regulator Performance: Error Amplifier Gain - The performance of a regulator is dependent on the voltage gain of the error amplifier. A higher gain amplifier gives better line and load regulation. So, anything that…
Important Points Regarding Working of Transistors: The noteworthy points regarding working of transistors are summarized below. 1. Current conduction in N-P-N transistor is by electrons and the conventional current flow will be in the opposite…
Important Definition of Phase Locked Loop (PLL): Some Important Definition of Phase Locked Loop PLL are as follows : Lock Range: When PLL is in lock, it can track frequency changes in the incoming signal.…
Impedance Matching using Half Sections: While connecting number of different sections in the filter, it is very important to match the impedances of the sections at the junction points. Thus a T section should not…
Impedance Matching and Tuning in Waveguide: We know that suitably chosen series or parallel pieces of transmission line had properties which made them useful for providing resistive or reactive impedances. It is the purpose of…
Impedance Diagram: Impedance Diagram is a complex quantity having real and imaginary parts; where the real part is the resistance and the imaginary part is the reactance of the circuit. Consider the RL series circuit…
Impedance Coupled Transistor Amplifier: A two-stage impedance coupled transistor amplifier using N-P-N transistors in CE configuration is shown in Fig. 16.37. The only difference between this circuit and R-C coupled transistor amplifier circuit is that…
Impedance and Phase Angle of Series Resonant Circuit: The impedance of a Series Resonant Circuit is The variation of XC and XL with frequency is shown in Fig. 8.4. At zero frequency, both XC and Z…
Impatt Diode Working: IMPATT Diode Working is a combination of delay involved in generating avalanche current multiplication, together with delay due to transit time through a drift space, provides the necessary 180° phase difference between…
