Semiconductor Electronics

In the logic circuit shown, inputs A and B are each first passed through a NOT gate, and the two outputs are then fed into a NOR gate to give output Y. The truth table for Y is:

  1. A.A B Y: 0 0 0 · 0 1 0 · 1 0 0 · 1 1 1
  2. B.A B Y: 0 0 0 · 0 1 1 · 1 0 1 · 1 1 1
  3. C.A B Y: 0 0 1 · 0 1 1 · 1 0 1 · 1 1 0
  4. D.A B Y: 0 0 1 · 0 1 0 · 1 0 0 · 1 1 0

You have the answer. The worked solution — and why the other three were written — is part of a paid pack.
