摘要
介绍了由单片机构成的４位数字信息采样系统。这一系统可将所关心的某段时间内的数字信息存储起来，在需要时用普通示波器显示。因此，利用这一系统和普通示波器，就可构成多通过数字信息存储示波器或简易逻辑分析仪。将软件和硬件稍加变化。
A 4-digit information sampling system with single-chip microcomputer is described. The digital information in a interested interval can be storaged by this system and displayed with a general purpose oscilloscope when required. Thus a multi-channel digital information storage oscilloscope or a simple logic analyzer can be composed by a general purpose oscilloscope pe and a single-chip microcomputer unit. 8-digit system is also obtainable by some modifications of software and hardware.
