一、前言当前数字技术的研究与应用在我国十分活跃。在研制数字系统的过程中,常常需要同时观测多路信号,以确定它们的逻辑关系是否正确。当然可用逻辑分析仪来进行多路观测,但这类仪器非常昂贵,例如美国TEK 公司的两种逻辑分析仪DAS9127和1241NO8的售价分别为32,562美元和31,970美元。因此现在用得 I. Introduction The current research and application of digital technology in our country is very active. In developing digital systems, it is often necessary to observe multiple signals simultaneously to determine if their logical relationship is correct. Of course, logic analyzers can be used for multiple observations. However, such instruments are very expensive. For example, the two logic analyzers DAS9127 and 1241NO8 manufactured by TEK of the United States are priced at 32,562 dollars and 31,970 dollars respectively. So now it works
