Other AbstractThe invention relates to a method and device for rapidly extracting a feeble signal. The device comprises an analog-to-digital converter for performing sampling to an original target signal of the mixed strong noise, a main control logic device used for receiving the sampled signal of the analog-to-digital converter and used for performing rapid extracting to the sampled signal by using the original characteristic vector extracted from a big target signal or through the circularly updated characteristic vector to obtain a discrete target signal by calculation, and a digital-to-analog converter for converting the finally extracted discrete target signal output by the main control logic device into an analog signal output. The method comprises the following steps: sampling the original target signal of the mixed strong noise rapidly extracting the sampled signal and the characteristic vector to obtain the discrete target signal of which the strong noise is removed and performing digital-to-analog conversion to the discrete target signal so as to output the ultimate target signal. The invention has the advantages of rapid extraction and high real-time.
