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…
Double Cage Rotor Induction Motor: A rotor design, which though more expensive gives still better starting, and running performances than the deep-bar design, is the Double Cage Rotor Induction Motor. The double squirrel cage induction…
Power in Three Phase Circuits: Measurement of power by a wattmeter in a single phase circuit can be extended to measure Power in Three Phase Circuits. From earlier Section, it is clear that we require…
Three Wire DC System Balancer Set: Although in a 3-wire d.c. system every effort is made to distribute the various loads equally on both sides of the neutral, yet it is difficult to achieve the…
Audio Amplifier Frequency Response: The Audio Amplifier Frequency Response is essential for filters, couplings circuits, amplifier stages and overall audio circuits. An amplifier stage is used as an example. A test setup for this amplifier…
Magnetic Flow Meters: Magnetic Flow Meters are the first type of flowmeters to be considered for high corrosive applications and for applications involving measurement of erosive slurries. These meters work on the principle of Faraday's…
Induction Type Directional Power Relay: This Induction Type Directional Power Relay operates when power in the circuit flows in a specific direction Unlike a non-directional overcurrent relay, a directional power relay is so designed that…
Introduction to Oscilloscopes: Introduction to Oscilloscopes - The Cathode Ray Oscilloscope is probably the most versatile tool for the development of electronic circuits and systems. The Cathode Ray Oscilloscope allows the amplitude of electrical signals,…
BCD Subtraction: Addition of signed BCD numbers can be performed by using 9's or 10's complement methods. A negative BCD number can be expressed by taking the 9's or 10's complement. Let us see BCD…
Generation of Amplitude Modulation: There are two types of devices in which it may be necessary to the Generation of Amplitude Modulation. The first of these, the AM transmitter, generates such high powers that its…
