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. Digital Signal Processing (DSP) in Oscilloscopes February, 2010 Kenneth W. Johnson Introduction Senior Product Marketing Manager 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 Summary phosphor-trace display models to digital storage types with long memory and extensive post-processing capability, the ability to debug and analyze The oscilloscope is the test circuits has greatly increased. In addition, the shift to digital primar……
