| Abstract: | The frequency features of the optical transient signal, the background signal and high frequency noise are analyzed, and the virtual instruments of signal processing are given based on LabVIEW. The design of the digital filter is introduced and the original signal is filtered, and then the spectrum estimation of the filtered signal gives the power spectrum density. The test result shows that the new method is simple, reliability and effective. |
