【Abstract】 Digital signal processing(digital signal processing,DSP) and electronic measurement and instrument(electronic measurement and instrument,EMI) are inseparable,which is already known for common sense. The effect of digital signal processing on electronic measurement instrument was the breakthrough point. The relationships of DSP and EMI were investigated one by one. Firstly the importance of measurement was explained,and then the performances of the main electronic measurement instruments improved by DSP were listed. Finally the traditional theory of measurement constraints broken by DSP and make the digital storage oscilloscope up to maximize the potential was discussed.更多还原
