Google Patents CA2233709C - Block coding for digital video transmission If you remember our previous example, we were a little surprised that true and true would still lead to true, somewhat unlike human reasoning.CA2233709C - Block coding for digital video transmission The correct lingo for an XOR gate is Exclusive OR. The XOR gate is also sometimes called EOR or EXOR. In other words, our logic works like this: 0 + 0 => 0Īll other gates (except for the NOT gate) are a little more tricky to comprehend, but stay tuned. ![]() ![]() Similar to our OR logic gate, the AND logic gate will process two inputs resulting in one output, but this time, we’re looking for both inputs to be true for the outcome to become true. This is a little offset from a human thinking about OR, as the word or is often associated with one or the other. Interestingly, if both inputs are true, the output will also be true. In all other cases, the output of our OR gate will be true. As you can see, the only way that our output could ever be false (i.e. Here, 0 represents false and 1 represents true. In other words, we can write an OR logic gate into this flowchart: 0 + 0 => 0 If you take a look at the header image, you can see how all logic gates have two inputs-except for the NOT logic gate, which has one input. ORĪn OR logic gate is a very simple gate/construct that basically says, “ I f my first input is true, or my second input is true, or both are true, then the outcome is true also.” Note how we have two inputs and one output. With the help of multiple logic gates, we can construct workflows that to some extent resemble or follow human thinking. While some logic gates are much more common (for example, an AND or OR gate is much more common than a NAND or NOR gate), all logic gates are sooner or later used to get a computer or electronic device to do exactly what’s required of it-to process data in a certain way. Such logic gates form the building blocks for much of the world’s code as well as for electronics. ![]()
