3.8 The transistor-level circuit below implements the logic equation givern below. Label the inputs to all the transistors. Y NOT (A AND (B OR C)) 3.15) If A and B are four-bit unsigned binary numbers, 0111 and 1011, complete the table obtained when using a two-bit full adder from Figure 3.15 to calculate each bit of the sum, S, of A and B. Check your answer by adding the decimal value of A and B and comparing the sum with S. Are the answers the same? Why or why not? Cin 0 out
