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. Show that the image frequency for an FM station does not fall in the range of 88.1-107.9 MHz, regardless of the choice of high- or low-side local oscillator.
What is the function of the signal in 8086? BHE signal means Bus High Enable signal. The BHE signal is made low when there is some read or write operation is carried out. i.e.
