波形形成 [bō xíng xíng chéng]
waveshaping
- 利用矩形波重建方法，将带噪声动作电位信号通过低通滤波器建立相应的矩形波，然后再采用计算机辅助设计法设计一个波形形成数字滤波器，使矩形波通过此滤波器后重建出纯净的细胞动作电位。
The whole processing procedure consists of three steps, i.e., inputting the noisy AP signal to a low-pass filter, constructing a corresponding square wave according to the output of the low-pass filter and then applying it to the wave forming filter to get noise free AP signal. - 由超声脉冲法获得4种检测信息――声速、波幅、频率和波形，从中提取3个特征量：平均声速、声速的离差系数和波幅的离差系数，利用模糊分析方法和人工神经网络相结合对GRC、加气混凝土、空心砖、实心砖、砌块5种墙体材料进行种类识别，形成一个智能化的、具有类似人脑功能的系统.经现场实测证明，判别的准确率达95%以上。
Three characteristic features,such as average velocity of sound,deviation coefficient of sound velocity,and deviation coefficient of amplitude are extracted from four kinds of testing data which are sound velocity,amplitude,frequency and waveform in this paper.Fuzzy analysis and artificial neural network are combined to form an intelligent system with similar functions to human brain to classify GRC,aerated concrete,hollow brick,solid brick and concrete block.The accuracy of this system is up to 95%in field tests.
