在现代通用数字计算机中,由于其容量大、速度快、功能强以及设备多、元件新颖,使得计算机中的信号具有自己的特点。迅速而准确地测量出这些信号,就将大大地提高计算机的调机速度与调机质量。而完成这一任务,单靠宽带示波器是不够的。在一架现代化的数字电子计算机中,其信号是各式各样的,因而,对示波器的功能就提出了各种不同的要求。要研制适应计算机用的示波器,了解一下计算机中的一些主要信号的特点是很有必要的。 In the modern digital computer, because of its large capacity, fast, powerful and equipment, novel components, making the computer signal has its own characteristics. Quick and accurate measurement of these signals, it will greatly improve the speed of the computer and adjust the machine quality. To accomplish this task, broadband oscilloscope alone is not enough. In a modern digital computer, the signal is varied and, therefore, various requirements are imposed on the functionality of the oscilloscope. To develop an oscilloscope for a computer, it is necessary to understand the characteristics of some of the major signals in a computer.
