AB  - An electro-acoustic transducer can be characterized by measuring its Impulse Response (IR). Usually the collected IR is then transformed by means of the Fourier Transform to get the complex frequency response. IR and complex frequency response form a pair of equivalent views of the same phenomena. An alternative joint time-frequency view of the system response can be achieved using Wavelet Transform and a color-map display. This work illustrates the implementation of the Wavelet Transform into a commercial measurement software and presents some practical results on different kinds of electro-acoustic systems.
