    1. construct this simple error-detection system,
    2. operate the circuit to observe its normal operation,
    3. disconnect (open) a transmission line (at A),
    4. operate the faulty circuit and observe its detection of an error, and
    5. demonstrate the error- detection system to your instructor.


  2. Refer to Fig. 12-1 (above). Is this error-detection system using even- or odd-parity?

  3. Using circuit simulation software

    1. construct this divide-by-60 counter circuit,
    2. operate the circuit to observe its normal operation, and
    3. demonstrate the divide-by-60 circuit to your instructor.
