\overset{―}{A} \cdot B

Explanation:

If $A = B = 1;$ then $A . B + A = 1.1 + 1 = 1$ then $\bar{A} . B = \bar{1} .1 = 0.1 = 0$

4

0.02

Explanation:

The criteria for sustained stable oscillations is $A_{V} β = 1$
$∴ β = \frac{1}{A_{V}} = \frac{1}{50} = 0.02$
$A_{V} \to$ voltage amplification
$β \to$ attenuation of feedback circuit.
