摘要
提出一种在数字化仪表实际电路开发前,利用MATLAB分析工具对数字化仪表的信号特性进行预处理的方法。该方法为具体设计开发提供信号处理算法的验证,可降低数字式仪表的开发风险,提高开发进度。最后以数字处理电磁流量计的工频干扰信号为例进行详细说明。
A method is presented by using MATLAB to preprocess and analyse the signal of digital instrument before the actual circuit is designed. The method can test arithmetic of signal processing, reduce risk of digital instrument development and quicken development process. In the end, the power-line interference from electromagnetic flowmeter signal is processed digitally as an example to explain.
