Combinational Logic Circuit Example Problems With Solutions



Combinational logic circuits are amongst the most commonly used in electrical and computer engineering. They are responsible for a wide range of complex functions, from controlling microprocessors to driving robot arms. Despite their complexity, combinational logic circuits can be broken down into simple components and analyzed using mathematical principles. In this article, we will look at some examples of combinational logic circuit problems and their solutions.

Let’s start with a classic: the full adder circuit. This circuit is usually used for adding two binary numbers, as well as for carrying a value if the result of the addition goes over one digit. To solve this problem, we first need to identify the inputs and outputs of the circuit. The inputs include A and B, which represent the two binary numbers, while the output is the sum of those two inputs — C. We can then construct an equation to describe the behavior of the circuit: C = A + B + Carry.

Now, let’s move on to a slightly more complex example: the multiplexer circuit. This circuit is used to select one of multiple input signals and output it to another location. To solve this problem, we first need to identify the inputs and outputs of the circuit. The inputs include the selection signal, S, and the data input signals, D0, D1, D2, etc. The output is the data output signal, Q. We can then construct an equation to describe the behavior of the circuit: Q = D0*S + D1*S + D2*S + ... + Dn*S.

Finally, we have a third example: the decoder circuit. This circuit is used to convert binary information into multiple outputs. To solve this problem, we first need to identify the inputs and outputs of the circuit. The inputs include the binary number, B, while the outputs are the individual data bits, d0, d1, d2, etc. We can then construct an equation to describe the behavior of the circuit: d0 = BAND1; d1 = BOR1; d2 = BXOR1; etc.

These are just three examples of combinational logic circuit problems and their solutions. With a bit of practice, engineers can become adept at solving any type of circuit puzzle. However, it’s always a good idea to consult resources such as textbooks or online tutorials, so that you can be sure to get the correct answer.
