What we have learnt
- Three-step procedure for troubleshooting digital circuits: fault detection, isolation, and remedial measures.
- Common types of internal and external faults that affect digital integrated circuits.
- The role of test and measuring equipment, such as digital multimeters and oscilloscopes, in troubleshooting digital circuits.
Key Concepts
- -- Fault Detection
- The process of identifying the nature of faults in a digital circuit by comparing its actual performance against the expected ideal performance.
- -- Fault Isolation
- Performing tests and measurements to pinpoint the location of faults within a circuit, using diagnostic tools.
- -- Remedial Measures
- Actions taken to repair or replace faulty components within a digital circuit after identifying and isolating the faults.
- -- Digital Multimeter (DMM)
- An instrument used for measuring electrical parameters such as voltage, current, and resistance in digital circuits.
- -- Clock Skew
- The variation in arrival times of clock signals at different components in sequential circuits, which can lead to erratic behavior.
