Types of Filters in Electronics: Types of filters in electronics may be of any physical form—electrical, mechanical, pneumatic, hyÂdraulic, acoustical, etc. The most commonly used filters are of the electrical…
What are Passive Filters?: Passive filters are mainly networks using inductors, capacitors and resistors. The classical theory employed was based on the image parameter theory which in turn was based…
What is an Operational Amplifier?: An Operational Amplifier is a dc amplifier having a high gain, of the order of 104 - 108. Such an amplifier can perform summing, integration,…
Thermocouple Connection: One of the most commonly used methods of measurement of moderately high temperature is the thermocouple effect. When a pair of wires made up of different metals is…
Linear Variable Differential Transformer (LVDT): The differential transformer is a passive inductive transformer. It is also known as a Linear Variable Differential Transformer (LVDT). The basic construction is as shown…
Detectors Types: The Detectors Types are as follows For low frequency, the most convenient detector is the vibration galvanometer. For ordinary laboratory work at frequencies up to a few 100 Hz,…
Wheatstone Bridge Diagram: A Wheatstone Bridge diagram in its simplest form consists of a network of four resistance arms forming a closed circuit, with a dc source of current applied…
Transistor Tester and its characteristics: The term Transistor Tester (or analyser) used in this text is for instruments giving quantative measurements of transistor parameters. The tester should be able to…
