Logic Gates
Have you ever wondered how a computer or other digital device can transmit a binary input into a function or a non-binary output? For most computers and similar devices, a logic gate likely plays a key role in that function.
Just as the word “gate” might imply, a logic gate takes input and gives a derived output from that data, almost as if the data is passing through a gate. Since computers and other devices use binary code to read and process information, they need a component that translates that code into something else. This is where the logic gate comes into play through a Boolean function.
Logic gates vary in complexity and capability. If you are working on a project that requires one, consider these key differences to make the right selection.
Simplicity: Single Binary Logic Gates
The various types of logic gates available vary in the simplicity of their functions. If you are searching for a gate to invert a single function, you should consider the NOT logic gate. These devices take a single binary input and simply invert it, meaning if a “1” is inputted, then a “0” will be the output reading.
More complex gates can take the input of multiple wires that give different readings and transmute them into a single output based on that data. The NOT gate is the only one that reads the input of a single wire. This means that if you need to have the input of multiple wires transmuted into a single reading, you should find a different type of logic gate.
Some gates, such as the AND gate and the OR gate, can take the data from two wires and produce a single output. If you choose between these two gates, your decision will depend upon the specific type of reading you are after.
More complicated gates, such as the NAND and the NOR, are used in computers and devices used in everyday life. Since they use one or the other, these gates are considered universal in nature. You can essentially produce any other type of logic gate.
Components: Transistors, Diodes, and Resistors
Most logic gates are comprised of various transistors, diodes, and resistors. Once again, The components you use will depend on what function you need it for. While most of the gates out there typically have an input of only two wires, you can combine them together to implement a single circuit if that is what your function demands.
The seven most common types of gates are AND, OR, XOR, NOT, NAND, NOR, and XNOR. You can likely choose from these to find the right fit for your project. Contact Perfect Afternoon to learn more about our services and how we can help with your next step.
