Q. Draw and explain a differential circuit
A differentiator is a high pass RC circuit having a very small time constant. It is a circuit which gives an output voltage proportional to the derivative of the input voltage. A high pass RC circuit is a circuit, which allows only high frequency to pass through.
The output current I = C dVi/dt.
∴ V out= Rcdvi/dt
∴Vo ∝ d (vi)/dt
For a high pass RC circuit to act as differentiator time constant (t) of the circuit (RC) should be very much less than the input time period (T). Here if we give a constant input we get no output. For sine wave as input we get cosine wave as output. For square wave we get narrow pulses as output.
Q. Express the waveform of the staircase type shown in Figure as a sum of step functions.
Q. Effect of feedback on sensitivity to parameter changes? A good control system, in general, should be rather insensitive to parameter variations, while it is still able to fo
Q. The block diagram of Figure represents a multi loop control system. (a) Determine the transfer function C(s)/R(s). (b) For G 2 G 3 H 2 = 1, evaluate C(s)/R(s).
The circuit is altered by replacing the capacitor, C1 with an inductor of 150mH and left with the switch in position (a) for a long time. At time t=0, the switch is moved from posi
