A digital oscilloscope is an electronic instrument used to visualize and analyze electrical signals. It displays voltage changes over time on a screen, allowing users to observe waveforms, measure signal properties, and troubleshoot electronic circuits. Unlike analog oscilloscopes, digital versions convert signals into digital data for more accurate and flexible analysis. These devices are widely used in various fields, including engineering, telecommunications, and medical diagnostics. Digital oscilloscopes often come with advanced features such as automatic measurements, storage capabilities, and connectivity options for data transfer. This makes them essential tools for both professionals and hobbyists working with electronics.
