Abstract

Dual channel analysis of acoustic signals is examined in order to propose solutions to the problems resulting from manipulation and interpretation errors. Special attention is given to phase shift problems, truncation error and time delay. The possibilities and limits of the coherence function are studied. Two-way conversation between instrument and computer is presented in a systematic way, with applications
