英文摘要 | The utility model relates to a quick extracting device of weak signals, which is provided with an analogue/digital converter which is used to sample primary target signals of mixed strong noise, a main control logic device which is used to receive sampling signals of the analogue/digital converter and is used to extract the sampling signals to calculate and obtain discretization target signals through utilizing original characteristic vectors which are extracted from big target signals or characteristic vectors which are circulated and updated, and a digital-analogue converter which is used to convert the discretization target signals which are output by the main control logic device and are extracted finally into analog signals to output. The quick extracting device has rapid extraction and strong practicability, can be used to extract the target signals which are submerged in noise rapidly to achieve the purpose of checking the target signals, a large-scale logic circuit is utilized to realize fast algorithm, and the quick extracting device is used in situations with few resources, rapid speed, low power consumption, and high requirements of real time performance. |
