Abstract:

A detailed study of traditional and modern analysis procedures is presented in the area of electroacoustical system evaluation. Several system analysis tools such as Tone Burst testing, Cumulative Decaying Spectra, the Wigner-Ville distribution, Group Delay and an All-pass Decomposition technique – known as the Delay Plane projection by Heyser – are compared. A group of fourth order Low-pass filters of the Butterworth, Bessel, Chebyshev, LaVerne Terrace and Linkwitz-Riley families, subjected to the above-mentioned methods, reveal the superiority of both the CDS and the All-pass decomposition technique over the traditional methods, in terms of interpretation and applicability.
