Q. Explain basic working of Integrators?
Figure shows a noninverting integrator, which can be seen to be a negative impedance converter added with a resistor and a capacitor. Noting that vo = 2v1 and i3 = v1/R, the total capacitor current is
which shows that the circuit functions as an integrator.
Replacing R2 in the inverting amplifier of Figure by a capacitance C results in the somewhat simpler integrator circuit shown in Figure, known as an inverting integrator, or Miller integrator. With ideal op-amp techniques, iC = iin = vin/R. The voltage across C is just vo, so that
which illustrates that the network behaves as an integrator with sign inversion.
Q. What is Traffic Intensity? Traffic Intensity: Traffic load on a given network may be on local switching unit, interoffice trunk lines or other common subsystem. For analyti
Why maximum power output is given by a machine at an efficiency of 50 percent?
Explain the Advantage of Synchronous Counters? The most significant advantage of synchronous counters is that there is no cumulative time delay because all flip-flops are trigg
Q. Explain Internal Data Bus? Internal Data Bus: A bus which operates only within internal circuitry of the CPU, communicating among internal caches of memory which are part of
Mode 1 In this mode transistor Q gets turned on by the positive output of the PWM. After that current flows through inductor L transistor Q then back to supply in thi
