Q. What is Miller integrator ?
MILLER INTEGRATOR : Consider a basic RC circuit in which the opening of switch provides a sweep voltage.Yhe waveform generated by this basic circuit is not exactly linear,even if the ratio of the sweep voltage and the supply voltage is kept high.The linearity can be improved if the feedback arrangement , such as Miller sweep circuit is made with this. Feedback can be provided if an auxiliary variable voltage generator is introduced in such a way that variable voltage is always equal to the voltage developed across the capacitor.
Q. The self-inductances of two coupled coils are L 11 and L 22 , and the mutual inductance between them is M. Show that the effective inductance of the two coils in series is give
3) A sine wave oscillator, in effect, converts
Hybrid Model for Two-port Network:- V 1 = h 11 i 1 + h 12 V 2 I 2 = h 1 i 1
Q. A transmitter is connected to an antenna by a transmission line for which ¯ Z 0 = R 0 = 5 0 . The transmitter source impedance is matched to the line, but the antenna is kno

Q. Consider the electromagnetic plunger shown in Figure. The λ-i relationship for the normal working range is experimentally found to be λ = Ki 2/3 /(x+t), where K is a constant. D
Disadvantages
Passive filters: Passive implementations of linear filters are based upon combinations of inductors (L), resistors (R), and capacitors (C). These sorts are collectively termed
GTO ( Gate Turn Off) GTO stands for gate turn off thyristor . it is four layer PNPN device. It can be triggered into conduction like a conventional thyristor by a pulse
Q. We have discussed three different color spaces: RGB, HSI and CMY(K). Specify the need for multiple color spaces. Why can we not use only one? Q. A telescope in an observatory
