Question

1. For the circuit given in Figure 1.11: • obtain the Boolean expression and the truth table of the circuit. • Implement the logic circuit of Figure 1.11 on the breadboard. Connect the inputs A, B and C to the switches and output to the LED of the lab-station. The pin diagram of different ICs is given in Figure 1.12. The three input OR gate can be implemented either using two OR gates or using a three input NOR gate with a NOT gate. • Obtain the truth table of the circuit by flipping the switches to an ON/OFF position and checking the output in each case.
