提出对诱发电位新的处理方法。内容包括从叠加、诱发电位振幅、诱发电位潜伏期、诱发电位记录和诱发电位发生器所涉及的叠加技术、记录数据采样技术和滤波技术 4方面。信号滤波和周期性叠加的技术可以增强诱发电位辨别率。为检测波峰潜伏期 ,可在连续波峰之间标识出潜伏期变化技术应用到商用诱发电位仪上。现代数字式记录仪是由感觉刺激器 ,具有模拟滤波的记录振幅 ,模拟数字转换器 ,数字信号叠加 ,显示和存储系统几部分 (过程 )组成。采样获取作用的发展趋势是以不同时间不同电压设置和不同采样率 ,多通道对刺激器所诱发的电位进行分析。随着数字滤波在模数转换上的应用 ,诱发电位的数据处理将会得到进一步的发展
A new treatment method for evoked potentials was proposed. The content includes four aspects: superposition, evoked potential amplitude, evoked potential latency, evoked potential recording and evoked potential generators involved in the overlay technology, recorded data sampling techniques and filtering techniques. Signal filtering and periodic superposition techniques can increase the discrimination of evoked potentials. To detect the peak latency, a latent period change technique can be identified between consecutive peaks and applied to a commercial evoked potential meter. Modern digital recorders are composed of a sensory stimulator, an analog filter with recording amplitude, an analog-to-digital converter, a digital signal superposition, and a display and storage system in several parts (processes). The development trend of sampling and acquisition is to analyze the potential induced by multiple stimulators with different voltage settings and different sampling rates at different times. With the application of digital filtering in analog-to-digital conversion, the data processing of evoked potentials will be further developed.
