What is the primary function of an oscilloscope?

The primary function of an oscilloscope is to visualize and analyze electronic signals. This instrument provides a graphical representation of voltage changes over time, allowing users to observe waveforms, signal amplitude, frequency, and various other characteristics of the electrical signals being monitored. By displaying these waveforms on a screen, oscilloscopes enable engineers and technicians to assess the behavior of signals in a circuit, troubleshoot issues, and ensure that circuits are operating within specified limits. The ability to analyze these waveforms is critical for diagnosing problems in electronic systems and is an essential tool in both design and testing phases of electronic projects.
