摘要：
The computer- or microprocessor-based signal processing technology is one of the demodulation and processing methods capable of suppressing noise interference and enhancing signal-to-noise ratio. In this paper, the technology of software filtering and demodulation based on wavelet transform is presented. According to the features of band-pass and time-frequency domain localization of wavelet transform, a linear combined wavelet transform is used to approach an ideal narrow-band filter, and the designed filter has a fine filtering character. It provides a more convenient method for signal demodulation analysis and multi-pass-band components filtering in engineering signal processing. It has been used in the case of optical current transformer and can be developed to other signal processing applications.
