Analysis and Performance Monitoring of Electro-acoustic Systems
Original language description
For analysis of electro-acoustic systems we concentrated on a method using swept harmonic signals. This method uses driving the system under test by logarithmically swept signal and recording the system response to the test signal. A socalled "inversionfilter" is derived from the exciting signal. By convolution of the system response with this inversion filter we obtain the impulse response of the system under test. During a large signal excitation or even overload of electro-acoustic systems, a non-linear distortion may take place. This phenomenon can be analyzed from responses obtained by this method. By appropriate selection of driving signal parameters we can determine the individual distorting components. The method proved especially suitable formonitoring of multichannel systems, where it is possible to observe performance of individual channels as well as their mutual interaction, crosstalk etc.
