Definition: A logic gate is a circuit with one or more input voltages but only one output voltages. logic gates are fundamental building blocks of the digital system. NOT, OR, and AND Gates are the basic types of gates. The interconnection of gates to perform a variety of logical operation is called logic design.

2.7 Symbols Used For Logic Gates When they design circuits, engineers think about interconnecting logic gates rather than interconnecting transistors. Each gate is represented by a symbol, and engineers draw diagrams that show the interconnections among gates. Figure 2.6 shows the sym-bols for nand, nor, inverter, and, or, and xor gates.

• In computing systems, the symbols 0 and 1 indicate 2 possible states of a circuit or device. The following logic gates will be treated in this lesson: • OR; • AND; • NOT; • XOR; • NOR; • NAND and • XNOR • Logic gates operate based on a logical algebraic system known as Boolean algebra.
