Answer
A=1, B=1
Step 1: Identify the gates and inputs.
The upper circuit has a 2-input AND gate with inputs 1 and 1, followed by a 2-input OR gate with the AND output and input 0, outputting to A.
The lower circuit has a 2-input AND gate with inputs 1 and 0, followed by a NOT gate (inverter), outputting to B.
Step 2: Compute upper AND gate (G1).
Substitute:
Step 3: Compute upper OR gate (G2 = A).
Substitute:
Step 4: Compute lower AND gate (G3).
Substitute:
Step 5: Compute lower NOT gate (G4 = B).
Substitute:
A = 1, B = 1
A=1, B=1
