Study of colored pseudo-noise for impulse response measurement

Abstract (in Japanese) (See Japanese page) 
(in English) SS( swept sine) and PN( pseudo noise) signals are used for impulse response measurement. The PN signal cannot increase its power relative to the SS signal, since the crest factor of the PN signal is high. In this study, we propose a method of reducing the crest factor to solve this problem. This method involves clipping a signal after interpolation while maintaining the original amplitude spectrum. By this method, the signal crest factor is decreased to less than √2 which is the crest factor of the SS signal. Also, we propose the MN-PN( minimum noise-pseudo noise) signal with a reduced crest factor. It is confirmed that the MN-PN signal has a higher noise reduction performance than the conventional MN-SS( minimum noise-swept sine) signal. Also, the superiority of the MN-PN signal over the MN-SS signal in terms of tolerance to nonstationary noise is confirmed.
