摘要
A digital signal processor for determining a property of a material flowing through a conduit. The digital signal processor of this invention receives signals from two pick-off sensor mounted at two different points along a flow tube at a first sample rate. The signals are converted to digital signals. The digital signals are decimated from a first sample rate to a desired sample rate. The frequency of the received signals is then determined from the digital signals at the desired sample rate.
