A Design of Multi-channel Digital Filter

In order to implement multi-channel real-time acquisition of hydroacoustic data, the design of a multi-channel digital geophone based on the MAX10M08 processor, which can perform multi-channel synchronous filtering processing of the signal received from the acoustic transducer, and the signal will be full-wave rectification output to achieve the signal geophone function. The design uses a highly integrated multi-channel data acquisition design approach to achieve the main functions, and after testing and verification, the results show that its detector function is normal, low power consumption, can be used for data multi-channel real-time acquisition.
