As a core of the ultrasonic flow meter which could control
This article describes a DSP-based digital signal processing module design of high speed
high precision.We realize the plan in the example of TMS320C6713 DSP and formulate it as follows:the high-speed transceiver of the waveform
the high-precision timing coordination and the configuration of parameters.Experiment results show that this design scheme can reduce the time error of flow calculation to ns-level accuracy in the condition of 75MHZ data transfer frequency.
