Cramer Rule: If the network is complex, the number of equations i.e. unknowns increases. In such case, the solution of simultaneous equations can be obtained by Cramer Rule for determinants. Let us say that set…
Instrumentation Amplifier or Data Amplifier: Instrumentation Amplifier - Many industrial systems, consumer systems and process control systems require a precise measurement of the physical quantities like temperature, pressure, humidity, weight etc. A sugar factory requires…
Electrical Energy Definition: Electrical Energy Definition states that energy is the basic necessity for the economic development of a country. Many functions necessary to present-day living grind to halt when the supply of energy stops.…
Introduction to Modern Power System Planning: In Modern Power System Planning, electric energy is an essential ingredient for the industrial and all-round development of any country. It is a coveted form of energy, because it…
Active Filters Interview Questions and Answers: 1. What is meant by ‘frequency response’ of a filter? Ans. A graph of the magnitude of the gain versus frequency is called a frequency response plot. 2. The gain…
MOSFET Biasing Circuits: DE-MOSFET Bias Circuits - DE-MOSFET bias circuits are similar to JFET bias circuits. Any of the FET bias circuits already discussed can be used to produce a negative VGS level for an…
Conversion of Hybrid Parameters in Transistor Three Configurations: Some transistor manufacturers provide only the four CE hybrid parameters while others provide CB hybrid parameters. Sometimes, for a specific purpose, it becomes necessary to convert one…
Controller Design Frequency Response: The Controller Design Frequency Response (or root locus) alters or reshapes the frequency response (or root locus) of the original system to the desired one. Thus the ideal goal of compensation…
n Stage Cascaded Amplifier: As already discussed, several amplifier stages are usually cascaded to increase the overall voltage gain of the amplifier. However, sometimes cascading is done to obtain the desired output and input impedance…
Chopper type DC Amplifier Voltmeter (Microvoltmeter): Chopper type DC Amplifier Voltmeter the dc input voltage is converted into an ac voltage, amplified by an ac amplifier and then converted back into a dc voltage proportional…
