Design of a Wavelet Filter for Experimental Error Improvement on Acoustic Decay Measurements
음 감쇠 측정에서 측정 오차 개선을 위한 웨이블렛 필터 설계
Abstract
It is well known that there are two experimental errors on acoustic decay measurements. One is due to the influence of the band pass filter the other one is that of an averaging device. In this paper the influence of the filter is in detail investigated. To minimize the influence of filter, the product of the filter bandwidth Β (3㏈ bandwidth) and the reverberation time T
