Abstract: An analysis of the error generation mechanisms that affect the accuracy of measurements of ultrasonic wave attenuation coefficient and phase velocity as functions of frequency is presented. Errors can originate from digital processing of acoustic signals however an appropriate sampling frequency, effective anti-aliasing filters, and the use of floating point computations of adequate precision for time-to-time frequency transformation render such errors negligible.
