Systems and methods for improved dynamic pressure measurements

摘要

A method, device, or system is provided for improving dynamic pressure measurements. In one embodiment, a method comprises receiving, at a filter structure having a restricting tube, an input pressure having a static pressure (P_S), a lower-frequency dynamic pressure (P_LD) and a higher-frequency dynamic pressure (P_HD); filtering, by the restricting tube, the input pressure to substantially pass an output pressure having the static pressure (P_S), the lower-frequency dynamic pressure (P_LD), and an attenuated higher-frequency dynamic pressure (P_HD); and outputting, from the filter structure, the output pressure.
