伪波 meaning in English

pseudo wave

We have successfully designed an experiment system for the no invasion blood pressure measurement with our own ip . in our research and develop task we have done a lot work to study foreign instrumen and design ideas . this experiment system is based on msp430 series mpu with excellent erformance and applies advanced digital signal process and intelligent technology . in hardware design , the following means were applied : after a lot of experment and fully knowing about the characteristic of the pulse wave signal , we have designed the accurate and credible circuit to collect the pulse wave signal ; power circuit , communicaion circuit , power drivers circuit have been disigned for the instrument . in software design , the following arithmetic were applied : 1
软件方面进行了以下算法研究: 1 .综合试验各种数字信号处理方法对波形进行平滑处理: 2 .采用lms自适应方法对脉搏波信号进行了降噪处理; 3 .应用微分闭值法提高了脉搏波信号的检出率，有效识别了运动干扰引起的伪波信号; 4 .利用测振法基本原理并进行大量实验的基础上，提出了比较准确可行的收缩压和舒张压的识别算法，使测振法在本无创血压仪中得到了完整而充分的应用。
