Abstract
In this work we propose a technique for analyzing microwave acoustic we use as analysis tool analysis the famous wavelet transform, it can analyze the signal locally and know its characteristics in a more precisely way. The signal to be processed represents the propagation of the microwaves acoustic in a piezoelectric structure excited by an interdigital transducer when the electroelastic wave propagation by surface deformation of this structure. As an application, these structures are used for the modeling of various electronic components in microwave such as filters and Acoustic wave amplifiers.
