Homework: Logic Gates
Part of Assignment 8

Fill in the truth table for the circuit below. Remember to find both inputs for a gate before you try to find the output, and to make a larger truth table to find the results in between the individual gates.

A

B

C

D

0

0

   

0

1

   

1

0

   

1

1

   

 

Treat this as four separate problems - a, b, c and d - one for each row of the truth table.

Find the outputs C and D for the following values of the inputs A and B:

  1. A = 0, B = 0

  2. A = 0, B = 1

  3. A = 1, B = 0

  4. A = 1, B = 1
