基于FPGA的闪电回击波形峰值提取算法研究

he characteristics of Lightning hit-back waveform is an important basis to study lightning, and the characteristics of the waveform epitomizes in the waveform peak, therefore getting the waveform peak is of great significance. Conventional waveform peak extraction algorithm is based on seeking maximum principle, which is appropriate for general waveforms, such as sine, triangle wave and other rules of the waveform. But for natural lightning come back waveform, the algorithm is slightly less than, the need to fight back waveform characteristics for further improvement. Extracted peak extraction algorithms based on the VHDL hardware programming language is not only applicable to conventional waveform, but also the peak of the hit-back waveform.
