There are three implementation schemes: the interdigital transducer, the meander line transducer and the grating transducer. Because the interdigital transducer has excellent properties, namely, good frequency characteristic and low insertion loss, we use the interdigital transducer as the implementation scheme of a single-scale wavelet transform processor using MSSW device. In the paper, we also present the solutions to the three key problems: the direct coupling between the input transducer and the output transducer, the insertion loss, and the loss characteristics of the gyromagnetic film having an influence on the wavelet transform processor. There are two methods of reducing the direct coupling between the input transducer and the output transducer: increasing the distance between the input transducer and the output transducer, and placing a metal “wall” between the input transducer and the output transducer. There also are two methods of reducing the insertion loss of a single-scale wavelet transform processor using a MSSW device for scale: the appropriate thickness of the yttrium iron garnet (YIG) film and the uniform magnetic field.The smaller the ferromagnetic resonance linewidth of the gyromagnetic film , the smaller the magnetostatic wave propagation loss.}, type={Artykuły / Articles}, title={Solution of Some Problems oOf Single-Scale Wavelet Transform Processor Using a Magnetostatic Surface Wave Device}, URL={http://www.czasopisma.pan.pl/Content/90014/PDF/Journal10178-VolumeXIXIssue4_06.pdf}, doi={10.2478/v10178-012-0060-5}, keywords={wavelet transform processor, magnetostatic surface wave (MSSW), interdigital transducer, direct coupling, insertion loss.}, }
