一、引言近年来,由于集成度高、价格便宜的微处理机芯片的问世,使得计算机在医学生理实验中的普遍应用成为可能。将微处理机与示波器、生物电放大器和刺激器等传统电生理仪器组合,使原有的实验系统由只具有单一的记录功能变为具有对某些生物电信号进行分析和处理的多种功能,是实验手段的一大进步。据此,我们研制了一台以 DBZ—80单板微机为主 I. INTRODUCTION In recent years, the advent of microprocessor chips with high integration and cheap prices has made it possible to widely use computers in medical physiology experiments. Combining microprocessors with traditional electrophysiological instruments such as oscilloscopes, bioelectric amplifiers and stimulators, the original experimental system has been transformed from having only a single recording function to having multiple functions for the analysis and processing of certain bioelectric signals , Is a big step forward in experimental methods. Accordingly, we developed a DBZ-80 veneer microcomputer
