In impulse response measurement, a time-invariant linear system is assumed. Therefore, measurement errors arise when there is temporal fluctuation in transmission systems caused by wind during measurement in a large space or a minute difference between the sampling periods of a digital-to-analog (DA) reproducing system and an analog-to-digital (AD) recording system. The magnitude of the errors depends on the type of measurement signal. The magnitude is small when a swept sine signal, such as a time-stretched pulse (TSP), is used; however, it is large when a pseudonoise signal, such as a maximum length sequence (M-sequence), is used. We consider that this error is caused by the fact that conventional white pseudonoise does not have a white continuous spectrum whereas its discrete spectrum is white. In this study, a new pseudonoise signal with a white continuous spectrum is proposed. We call this new signal a “pure white pseudonoise signal”, and its generation algorithm is presented. Simulations and experiments in a real environment show the effectiveness of the pure white pseudonoise signal for ensuring tolerance to time axis fluctuation. |
