摘要
Abstract
The multiplexer acts 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 wdiole process is controlled by the FPGA. Finally, by the DAC-ADC joint debugging, in compare to the results, 14bit precision is guaranteed with ADC.关键词
