Digital Circuit Testing

As a critical step in digital circuit design, digital circuit testing verifies whether circuits function as expected. Oscilloscopes are usually used to examine output signals in digital circuit testing for the purpose of troubleshooting and circuit performance and parameter verification. With varying bandwidths and sampling rates, different oscilloscopes provide tailored optimal measurement solutions for diverse types of circuits. This page describes how to use an oscilloscope for debugging a typical digital circuit.
