文章探讨了运用SystemView软件,从图形化的工具和数字化的指标入手,抛开传统滤波器设计中繁琐的计算与变换,直接快速实现了在数字存储示波器中,为了消除前端系统本身的噪声而设计的FRI数字滤波器。并且运用SystemView软件的分析工具,对所设计的FRI数字滤波器的幅频特性、相频特性、阻带衰减、通带纹波等性能进行了分析。通过分析报表和特性图形显示所设计的FRI数字滤波器技术指标完全满足数字存储示波器系统的技术要求。
The article discusses the use of SystemView software, starting from the graphical tools and digital indicators, aside from the cumbersome calculation and transformation of the traditional filter design, direct and fast in the digital storage oscilloscope, in order to eliminate the noise of the front-end system itself FRI digital filter. And the analysis tools of SystemView software are used to analyze the amplitude-frequency characteristic, phase-frequency characteristic, stop-band attenuation and pass-band ripple of the designed FRI digital filter. By analyzing the report and the characteristics of graphical display FRI digital filter design specifications to fully meet the technical requirements of digital storage oscilloscope system.
