| Abstract: | A data acquisition system for precipitation based on optical shadowgraph is presented,the system consists of high-precision float-point DSP TMS320F28335 and analogy-digital converter AD9240 of ADI,and the signal processing circuit is simulated with Proteus.Preliminary experiment results show that the signal processing circuit can meet the measurement require,and the designed data acquisition system can better acquire the simulated precipitation signal. |
| Keywords: | optical shadowgraph precipitation data acquisition TMS320F28335 AD9240 |
