AC Voltmeter using Rectifiers: AC Voltmeter using Rectifiers - Rectifier type instruments generally use a PMMC movement along with a rectifier arrangement. Silicon diodes are preferred because of their low…
What is Sinusoidal Pulse Width Modulation?: In Sinusoidal Pulse Width Modulation the pulse-width instead of being uniform as in the waveform of Fig. 11.55 is a sinusoidal function of its…
Wien Bridge Oscillator using Op Amp: This is also RC oscillator which uses RC type of feedback network. The main difference between phase shift and Wien bridge oscillator is that…
Ideal Active Op Amp Differentiator circuit: The circuit which produces the differentiation of the input voltage at its output is called Differentiator. The differentiator circuit which does not use any…
Op Amp Integrator Circuit: In an Op Amp Integrator Circuit, the output voltage is the integration of the input voltage. The integrators circuit can be obtained without using active devices…
Important Questions of Integrated Circuits: Give classification of integrated circuits. Compare IC families on the basis of substrate used, structure, active devices, passive devices and applications. What are the different…
MMF of AC Distributed Winding: It has been seen earlier that the armature what-when-how.comof a practical machine has distributed winding wound for the same number of poles as the field…
Harmonic Analysis in Distributed Winding: The flux density wave of a synchronous machine is never exactly sine wave. Because of odd symmetry of poles (alternately north-south), the space Harmonic Analysis…
