Ex-OR and Ex-NOR Gates problems

1. Identify the type of gate below from the equation
Options
A. Ex-NOR gate
B. OR gate
C. Ex-OR gate
D. NAND gate

Correct Answer: Ex-OR gate

2. The Ex-NOR is sometimes called the equality gate.
Options
A. True
B. False

Correct Answer: True

3. The odd/even parity system would require a sixth bit to be added to a 4-bit system.
Options
A. True
B. False

Correct Answer: False

4. In an exclusive-OR, both inputs cannot be HIGH to provide a HIGH output.
Options
A. True
B. False

Correct Answer: True

5. Using the CPLD design environment, we can simulate any combinations of inputs and observe the resulting output to check for proper circuit operation.
Options
A. True
B. False

Correct Answer: True

6. In a parity generator circuit, an error is signaled on an error indicator.

A. True
B. False

Correct Answer: False

7. Parity generator and checker circuits are available in single IC packages.
Options
A. True
B. False

Correct Answer: True

8. Electrical noise does not affect the transmission of binary information.
Options
A. True
B. False

Correct Answer: False

9. The exclusive-OR provides a LOW input if one input or the other input is HIGH.
Options
A. True
B. False

Correct Answer: False

10. 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.
