Q. Can you explain Noninverting Amplifier?
It is called "noninverting" because there is no sign inversion. A typical circuit is shown in Figure. With a finite op-amp gain Ao,
Since the ideal op amp draws no current,
i1 = i2
Also, as seen from Figure,
v2 = vi
In equating Equations, one gets
which is the gain of an ideal voltage follower. The same result applies if R1 →∞ (i.e., open circuit) for any finite R2.
Preventing Leakages at Insulators Leakages at insulators, cracking of insulators and flashover across insulators frequent cause outages and give output in loss of revenue. Pol
Consider the 220-V, 1800-r/min dc motor, controlled by a three-phase fully controlled rectifier from a 60-Hz ac source. The armature-circuit resistance and inductance are 1.5 and
Q. Explain Integral-error or reset control? A control system is said to possess integral-error control when the generation of the output in some way depends upon the integral o

Define Time and Shift Invariant? Time and shift invariant means that the system characteristics and shift do not change with time, i.e. the system output is independent of the
What is the function of DMA address register? Every DMA channel has one DMA address register. The function of this register is to keep the address of the starting memory locati
having looked at the circuit, i first wanted to start my frequency from 0 and plot for 10000 to 20000. so in matlab i used f = 0:10000:20000; but the equation for frequency is f= 1
