Transfer-Function Measurement with Sweeps
Swen Müller,Paulo Massarani +1 more
TL;DR: In this article, the transfer function measurements using sweeps as excitation signals rather than pseudonoise signals have been investigated and shown to have significantly higher immunity against distortion and time variance.
Journal ArticleDOI
Angle-dependent in-situ measurements of reflection coefficients using a subtraction technique
TL;DR: In this paper, an improved PC-based method of measuring the complex reflection coefficient in situ for perpendicular and oblique sound incidence is described, where the direct sound is cancelled by subtraction with a previously obtained pseudo-free-field response.
Journal ArticleDOI
Integration of Frequency Response Measurement Capabilities in Digital Controllers for DC–DC Converters
TL;DR: In this paper, the authors demonstrate the feasibility of incorporating fully automated frequency response measurement capabilities in digital PWM controllers at relatively low additional cost using a Verilog-coded implementation with low tens of thousands of logic gates and about 10 kB of memory.

Measurement of the sound-absorption coefficient in situ: The reflection method using periodic pseudo-random sequences of maximum length
TL;DR: In this article, the problem of measuring the sound-absorption coefficient in situ is approached in a systematic way, accounting for parasitic reflections and background noise, and the basic reflection method is improved by using pseudo-random binary sequences of maximum length as the test signal.
