The comb waveform as an efficient method for wideband measurements

An efficient acoustic calibration technique based on a uniformly‐weighted comb waveform is presented. The method takes advantage of the linear, time invariant nature of the measurement configuration and the comb’s wide bandwidth to capture all spectral components of interest for a device under test in a single ping. Results comparing single ping comb measurements with conventionally obtained CW measurements are presented. The examples given illustrate the accuracy and utility of this technique for the calibration of broadband systems.
