LCD Digital Storage Oscilloscope

It is a well established fact that the oscilloscope has made great progress. With digital technology,an oscilloscope has become an intelligent instrument with functions:waveform display,parameter measure,detecting,analyze,storage,and so on. But at the same time,it is not an easy task to build a system of oscilloscope because of many intractable problems. The article involves in resolving following questions:the method of bandwidth sampling,the efficient memory storage,the arithmetic of waveform interpolation,the friendly operation interface,the digital signal processing,embedded system,signal integrity,and so on. Besides,lots of work has been done to develop a physical instrument of LCD digital storage oscilloscope and it is a benefit for theory research.
