Form the truth table for an 8-to-3 priority encoder. Use W7 W6 W5 W4 W3 W2 W₁ Wo as inputs and y2 Y₁ Yo z as outputs. Derive the simplified Boolean expressions for y2 and z.

I need answer within 20 minutes please please with my best wishes

5. The resistors, labeled A through F, in the following circuit represent incandescent lightbulbs which are dimmable. By "dimmable," we mean the amount of light a bulb produces is proportional to the voltage across the bulb (or, correspondingly, the current through the bulb). The resistances of all these bulbs is constant and they all have the same resistance. Assuming the voltage source is sufficient to cause all these bulbs to produce at least some illumination, rank the bulbs from brightest to dimmest (if two bulbs are equally bright, note this fact). Justify your answer. You should be able to do this without using equations. (However, if you want to resort to an equation or two to help you sort this out or discuss your solution, that's okay.)
