- B. odd, even, bit
- C. upper, lower, digit
- D. on, off, decimal
- Correct Answer
- odd, even, bit
- 1. A logic circuit that provides a HIGH output for both inputs HIGH or both inputs LOW is a(n):
Options- A. Ex-NOR gate
- B. OR gate
- C. Ex-OR gate
- D. NAND gate Discuss
- 2. Determine odd parity for each of the following data words:
1011101 11110111 1001101
Options- A. P = 1, P = 1, P = 0
- B. P = 0, P = 0, P = 0
- C. P = 1, P = 1, P = 1
- D. P = 0, P = 0, P = 1 Discuss
- 3. Why is an exclusive-NOR gate also called an equality gate?
Options- A. The output is false if the inputs are equal.
- B. The output is true if the inputs are opposite.
- C. The output is true if the inputs are equal. Discuss
- 4. The decimal number 188 is equal to the binary number ________.
Options- A. 10111100
- B. 0111000
- C. 1100011
- D. 1111000 Discuss
- 5. Convert 73116 to decimal.
Options- A. 216.4
- B. 985
- C. 3D9
- D. 1841 Discuss
- 6. How is odd parity generated differently from even parity?
Options- A. The first output is inverted.
- B. The last output is inverted. Discuss
- 7. 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.
Options- A. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the same as B.
- B. Using A as the control, when A = 0, X is the same as B. When A = 1, X is the inverse of B.
- C. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the same as B.
- D. Using A as the control, when A = 0, X is the inverse of B. When A = 1, X is the inverse of B. Discuss

- D. NAND gate Discuss
- 9. Select the statement that best describes the parity method of error detection:
Options- A. Parity checking is best suited for detecting double-bit errors that occur during the transmission of codes from one location to another.
- B. Parity checking is not suitable for detecting single-bit errors in transmitted codes.
- C. Parity checking is best suited for detecting single-bit errors in transmitted codes.
- D. Parity checking is capable of detecting and correcting errors in transmitted codes. Discuss
- 10. The Ex-NOR is sometimes called the ________.
Options- A. parity gate
- B. equality gate
- C. inverted OR
- D. parity gate or the equality gate Discuss
