Data acquisition system based on time division multiplexing multichannel FIR (Finite Impulse Response) filter structure

The invention relates to a data acquisition system based on a time division multiplexing multichannel FIR filter structure, and the system comprises an analog signal acquisition module which comprises a plurality of mutually independent analog voltage signal acquisition channels and is used for collecting a target signal and converting the collected analog voltage signal into a digital voltage signal; the digital signal processing module is used for decoding the digital voltage signal and recoding the filtered digital voltage signal; the data processing module is used for processing the recoded signal output by the digital signal processing module, receiving an instruction, feeding back the instruction to the analog signal acquisition module and outputting a processing result according to the instruction; the analog signal acquisition module, the digital signal processing module and the data processing module are connected through an FMC socket. The data acquisition system has a good input bandwidth range whi
