# Lesson : Combinational Logic Circuit Exercises

We recommend having the cheat sheet for this chapter to help you solve the exercises.

Exercise 1:

In the first exercise, you will need to find the output value of the combinational logic circuit. The inputs of the circuit will be set at a specific value (either 0 or 1). You can find the circuit below :  $Output$:

Exercise 2:

In the second exercise, you will need to complete the truth table for this circuit. You can find the circuit below :  $\begin{array}{c c c|c} A & B & C & Output\\ \hline 0 & 0 & 0 & Output\ 0 \\ 0 & 0 & 1 & Output\ 1 \\ 0 & 1 & 0 & Output\ 2 \\ 0 & 1 & 1 & Output\ 3 \\ 1 & 0 & 0 & Output\ 4 \\ 1 & 0 & 1 & Output\ 5 \\ 1 & 1 & 0 & Output\ 6 \\ 1 & 1 & 1 & Output\ 7 \end{array}$ $Output\ 0$: $Output\ 1$: $Output\ 2$: $Output\ 3$: $Output\ 4$: $Output\ 5$: $Output\ 6$: $Output\ 7$:

You now have completed the Chapter 3 of Learn Electronics. In the next chapter, we will explore the binary system. We will see how to count in binary and how to do basics mathematical operation (addition and subtraction) in the binary system.
