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.
Q. Sampling of digital communication systems? Sampling of an analog signal makes it discrete in time. A bandlimited signal can be recovered exactly from its samples, taken peri

1- Use 4-to-16 decoder and some residue gates to recognize the following functions F1(A,B,C)= S(1,2,4,5,7) F2(A,B,C,D)= S(1,2,4,5,7,10,12,14,15) F3(A,B,C,D,E)= S(1,2,4,5,7,10,12,1
Q. Using a minimum number of NAND gates, realize the following Boolean expression: F(A,B,C) = ∑ mi (0, 3, 4, 5, 7).
Q. Explain Read-only memory? ROM is nonvolatile (because it maintains its contents even when its power is shut off) and is used to store data and programs that do not change du
