Troubleshooting should include
- constructing a logic circuit from a Boolean expression
- performing a functional check of the circuit
- formulating a truth table based on the results of the functional test
- performing troubleshooting procedures to locate the faulty IC and the faulty gate circuit within that IC
- removing and replacing the faulty component and repeating the functional check.
Process/Skill Questions:
- What indication on the logic probe means the IC has no power?
- What are the first steps in troubleshooting any logic circuit?
- How can a Boolean expression be used to explain the workings of a circuit?
