The XNOR gate is a digital logic gate that is the inverse of the XOR gate. It outputs a HIGH (1) signal only when both its inputs are LOW (0), and a LOW (0) signal otherwise.

Logic gates are the bricks and mortar of digital electronics, implementing a logical operation on one or more binary inputs to produce a single output. These operations are what make all computatio… ...

It’s time to do a series on logic including things such as programmable logic, state machines, and the lesser known demons such as switching hazards. It is best to start at the beginning &#82… ...

When studying logic, one must begin with the basic functions. Input values can be combined using the logical AND, OR, and exclusive OR (XOR) functions (Fig. 1 at right). Logic gates use digital ...

Here are some neat things that can be done at gate inputs, assuming they are Schmitt-trigger gates (Figure 6). Figure 6: Use Schmitt-trigger XOR, OR, or AND gates to make pulse shapers. More details ...

If the standard AND or OR logic elements are easily replaced by diode-resistive circuits, then the situation is much more complicated for XOR elements. It is worth noting that 3XOR logic gates are not ...

Using this approach, the researchers were able to make ultrafast (less than 100 fs operating time) all-optical XNOR, NOR, AND, XOR, OR and NAND logic gates, as well as a half-adder. And that’s not all ...

NAND gates are significant because any Boolean function (AND, OR, NOT, XOR, XNOR), which play a basic role in the design of computer chips, can be implemented by using a combination of NAND gates.
