Q. Explain about Differentiator?
Shown in Figure is a differentiator which is obtained by replacing R1 in the inverting amplifier of Figure by a capacitor C. Assuming ideal op-amp characteristics, one has i = iC and vo = - Ri = - RiC. But since iC (t) = Cdvin (t) /dt ,we get
vo (t) = - RC dvin (t) / dt
which corresponds to a differentiator with a gain of -RC. In practice, however, differentiators are normally avoided because of high-frequency noise (which is accentuated due to a transfer function that increases with frequency) and stability problems (which make them oscillate).

For the circuit of Figure, obtain the complete solution for the current i L (t) through the 5-H inductor and the voltage v x (t) across the 6- resistor.
A uniform quantizer is said to have 16 levels, and hence is called a midriser. The saturation levels are to correspond to extreme values of the message of 1 V ≤ f(t) ≤ 17 V. Find
I want to make project plz help me n gove me idea about actually its my first year in electrical engineering thts why Ineed help hpfully you will reply soon
In practice, it is usually better to wind the field coils on the rotor and supply the field current to them via slip rings. As the rotor turns, the changing magnetic field expe
