Digital Signal Processing (DSP) in Oscilloscopes

The oscilloscope is the primary tool used by hardware design and test engineers. Understanding how DSP is used in modern digital oscilloscopes is key to understanding the performance advantages that can be obtained, and avoiding the pitfalls of poor implementations.

The oscilloscope’s ability to faithfully and accurately reproduce the
electrical signal in a test circuit is the fundamental expectation an engineer
has when using one. As oscilloscopes have evolved from early analog
