Popis:	We apply the Padé-Laplace algorithm to automatically extract from DLTS multi-exponential transient decay measurements, the amplitude and the time constant of each discrete exponential component as well as the number of components without a priori assumption. Then, after setting restriction on the resolution of the multi-exponential problem itself due to noise, we present the field of this method numerical validity. Finally, the performance obtained on real signals is shown.
