Ex-OR and Ex-NOR Gates Questions

• Why is an exclusive-NOR gate also called an equality gate?
• Determine odd parity for each of the following data words: 1011101 11110111 1001101
• A logic circuit that provides a HIGH output for both inputs HIGH or both inputs LOW is a(n):
• Parity systems are defined as either________ or ________ and will add an extra ________ to the digital information being transmitted.
• How is odd parity generated differently from even parity?
• Show from the truth table how an exclusive-OR gate can be used to invert the data on one input if the other input is a special control function.
• A logic circuit that provides a HIGH output if one input or the other input, but not both, is HIGH, is a(n):
• Select the statement that best describes the parity method of error detection:
• The Ex-NOR is sometimes called the ________.
• Which type of gate can be used to add two bits?
• Identify the type of gate below from the equation
• The Ex-NOR is sometimes called the equality gate.
• 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.
