| Abstract: | A multi-channel analog signal sampling system which is based on DSP is presented in this paper.The core of the system is a fixed-point TMS320VC5409 DSP chip from TI Corporation.The chip reads and restores the converted digital data from AD7864 through those control signals that are produced by a CPLD circuit,which realizes the function to sample analog signals.The system has been applied into a lot of equipment including the underwater passive position sets. |
