摘要
在强噪声干扰下恢复有阶跃点的奇异波形或检测其参数在通讯、生物医学工程、图像处理中具有重要的意义．本文提出重建矩形波的理论及５种设计方法．通过处理、识别、重建３个步骤，能达到通常线性、非线性、时变滤波器很难达到的效果．
Restoration of signals, which are characterized by a rapid step or upstrolce, or detection of their parameters plays an important role in communications, biomedical engineering and image processing. In this paper we present the theory and five design methods forsquarewave restoration. By the three steps of processing the signal, detecting the characteristic parameters and then reconstructing squarewave, this technique can achieve results as common linear, nonlinear and time--varying filters can hardly yield.
