| Abstract: | An improved curve fitting for the resolution of the overlapped peaks was proposed. The main work is to use the continuous wavelet transform (CWT) to sharpen peaks and get reasonable initial estimates for the parameters of each peak. As a result, the fitted condition was improved and accurate results could be acquired. To verify the suggested method, separation of several kinds of overlapping peaks simulated by computer and the experimental voltammogram have been performed and are discussed. |
