| Abstract: | 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. |
