Abstract Aiming at the analysis and calibration of complex signal waveforms, a complex signal waveform decomposition and synthesis method based on waveform events is proposed. First, the waveform events are classified into periodic events and non-periodic events. For periodic events, they are decomposed in order from high amplitude to low amplitude, simplifying complexity and reducing the complexity and technical difficulty of complex waveform analysis. After decomposition of the periodic event, the rest is a non-periodic event, including single event and random event. By decomposing complex waveforms by event, the accurate positioning of each event on the complex waveform can be obtained, and the effective separation of each event from the parent waveform can be achieved. By the experiments and analysis on a set of complex signal waveforms based on disturbed sine waves, both the effectiveness and feasibility of the method described in the article are verified.
