Comparison of Three Linear Digital Filters Applied to Improve the Quality of the Measured Acoustic Field

Comparison of Three Linear Digital Filters Applied to Improve the Quality of the Measured Acoustic Field

The measurement of acoustic fields generated by ultrasonic transducers is important for determining the focal length, lateral resolution, and amplitudes of the lateral and grating lobes. The acoustic field is commonly characterized by a set of scans using a needle hydrophone. The output of the hydro...
