A Multi-Channel Data Acquisition System and its Performance Analysis Method Based on FPGA

The multiplexer act as the inputs of analog signals, enabling multi-channel analog signal acquisition; then filtered through a certain signal processing to ensure the most effective analog signals into the ADC; after conversion, the digital output is saved in the temporary buffer zone of the FPGA. The whole process is controlled by the FPGA. Finally, apply to the DAC-ADC joint debugging, in compare to the results, 14bit precision is guaranteed.
