Summary of the Basic Logic Gates and IEEE/IEC Standard Logic Symbols

• The three basic logic gates are the AND, OR and the Inverter.
• The NAND gate is a combination of an AND gate followed by an inverter.
• The NOR gate is a combination of an OR gate followed by an inverter.
• There is a new IEEE/IEC standard for logic symbols that allows the reader to determine the logic function simply by interpreting the notions on the symbol.
