A digital signal processor (291) for determining a property of a material flowing through a conduit (103A-103B). The digital signal processor (201) of this invention receives signals from two pick-off sensors (105-105') mounted at two different points along a flow tube at a first sample rate. The signal s 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 ra te.
