If an input, say input A, occurs twice in the boolean expression then there will be two references to it in the logic circuit diagram. A logic gate is a piece of an electronic circuit, that can be used to implement Boolean expressions. Employee barely working due to Mental Health issues. Every logic expression can be described with the truth table. a logic circuit to solve a given problem XOR As shown before, when we write an XOR in a Boolean Expression, we use the special symbol ⊕ - look closely and you’ll see that it uses an alternative for the OR symbol (+) and draws a circle around it to show it’s exclusive. You were paying attention in class that day, right? When you convert a boolean expression to a logic circuit diagram there is the possibility that there are more than one reference to the same input. Laws and theorems of Boolean logic are used to manipulate the Boolean expressions and logic gates are used to implement these Boolean expressions in digital electronics.
