Acquisition method and device for carrying out said method

The invention of for a method, and capture method and Bit length, wherein the code the expansion sequence, and secondary retards each time reaches 1) of the cylinder has for generating and local, a mm thick relevances replied. Retards each relevance to acknowledge, form the related result under with an then related acknowledge, here, the same is an thick and Blades integral multiples. Finally and maximum value search and are related results. Used to implement the method and device, has instrument end of the accumulator's first input end, it has instrument output by the delay network is the input end of the storage battery.
