Second Order High Pass Butterworth Filter Derivation: As in the case of a first order filter, a second order high pass filter can be formed from a second order low…
Second Order Low Pass Butterworth Filter Derivation: A stop band response having a 40 db/decade roll off is obtained with a Second Order Low Pass Butterworth Filter Derivation A second…
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…
What is a Photodiode?: A reverse biased Semiconductor diode passes only a very small leakage current (a fraction of 1μA in silicon diodes), if the junction is exposed to light.…
Working Principle of Piezoelectric Transducer: A symmetrical crystalline materials such as Quartz, Rochelle salt and Barium titanate produce an emf when they are placed under stress. This property is used…
