What is Logic Gates?
What is Logic Gates? Introduction Logic gates serve as the building blocks to digital logic circuits using combinational logic. We're going to consider the following gates: NOT gates (also called inverters), AND gates, OR gates, NAND gates, NOR gates, XOR gates, and XNOR gates. We'll also discuss the concept of gate deltay. NOT gates NOT gates or inverters have a single bit input and a single bit of output. This is a diagram of a NOT gate. It is a triangle with a circle on the right. The circle indicates "negation". The truth table defines the behavior of this gate. x z 0 1 1 0 where x is the input and z is the output. AND 2 gates AND 2 gates have two bits of input and a single bit of output. The subscript, 2, indicates how many inputs this AND gate has. For example, AND 3 gates have 3 inputs. The output of AND 2 gate is 1 only if both inputs are...
