作者用国产APPLE IIe兼容微机对7S11A(日本产)信息处理机的功能进一步扩展.该系统由7S11A信息处理机、APPLE IIe微机以及8位AD/DA卡组成.软件用BASIC语言及汇编语言编写.微机从7S11A的X-Y记录仪的Y通道采样,每扫描窗采样1024点数据,以保持7S11A原有的精度.扩展后,该系统能将诱发电位模拟信号数字化后存盘,波形自动分析、打印,波形展宽,存盘资料处理及听觉诱发电位的频阈分析等功能,为临床及科研提供更方便、更先进的分析手段.
The author further expands the capabilities of the 7S11A (Japan-based) Information Processor with a domestic APPLE IIe-compatible microcomputer, which consists of a 7S11A processor, an APPLE IIe microcomputer, and an 8-bit AD / DA card written in BASIC and assembly language. The computer samples from the Y channel of 7S11A XY recorder and samples 1024 points per scanning window to maintain the original accuracy of 7S11A.After the expansion, the system digitizes the evoked potential analog signal and saves it. The waveform analysis, printing, waveform Broadening, save data processing and auditory evoked potential frequency threshold analysis and other functions for clinical and research to provide more convenient and more advanced analytical tools.
