The Verilog reduction operators are used to convert vectors to scalars. The Boolean function is same for the 3- input XNOR gate is. Again, a high-output value at the gate output is interpreted as a logical 1, while an unconnected (floating) output is interpreted as a logical 0. Using a NAND or NOR Gate As a NOT: Simple trick to using a NAND or NOR gate to create an Inverter or NOT gate. This is the main principle in the half adder and the combined AND – XOR circuit may be chained together in order to add ever longer binary numbers. NOR gate gives an output of 1 if both inputs are 0, otherwise 0. An XOR gate (sometimes referred to by its extended name, Exclusive OR gate) is a digital logic gate with two or more inputs and one output that performs exclusive disjunction. , if you really had to use those switches. XOR + NAND Inverter(NOT) = XNOR i. These states correspond to the outputs of logic gates, allowing solutions of the triad to perform either NOT-OR (NOR) or exclusive OR (XOR) functions using only optical inputs and outputs. XOR Gate in combination to other basic can be wired to form Half Adder and Full Adder circuit. An XOR gate is made by considering the conjunctive normal form (+) ⋅ (¯ + ¯), noting from de Morgan's Law that a NOR gate is an inverted-input AND gate. Once it is converted to POS, then it's very easy to implement using NOR gate. If we observe carefully, OUT equal B' when A is '0'. 15 using any of the standard logic gates that are given in Table 3. Whereas the OR function returns true if any logical is TRUE, XOR returns TRUE in specific cases.
