The Ex-NOR is sometimes called the equality gate.

More Questions from Ex-OR and Ex-NOR Gates

• The odd/even parity system would require a sixth bit to be added to a 4-bit system.
• In an exclusive-OR, both inputs cannot be HIGH to provide a HIGH output.
• Using the CPLD design environment, we can simulate any combinations of inputs and observe the resulting output to check for proper circuit operation.
• In a parity generator circuit, an error is signaled on an error indicator.
• Parity generator and checker circuits are available in single IC packages.
• Electrical noise does not affect the transmission of binary information.
• The exclusive-OR provides a LOW input if one input or the other input is HIGH.
• A parity checker is constructed in the same way as a parity generator, except that in a 4-bit system there must be five inputs, and the output is used as the error indicator.
• The exclusive-OR is written in a Boolean equation as a plus sign with a circle around it.
