Implementing single-scale wavelet transform processor with magnetostatic surface wave device

Abstract

When the envelope of the conducting strips for the input transducer of magnetostatic surface wave (MSSW) device is designed according to the wavelet-function envelope, the impulse-response function of the input transducer for MSSW device is equal to the wavelet function, so that single-scale wavelet-transform processor of MSSW type is fabricated. First, according to the envelope function of the wavelet, the length function of the conducting strips is defined, then, the lengths of the conducting strips can be calculated from the length function of the conducting strips, finally, the input transducer can be designed according to the lengths and widths for the conducting strips. The compensation method of the insertion loss for single-scale wavelet transform processor of MSSW type is also given in the paper. When the output end of single-scale wavelet transform processor of MSSW type is connected to the amplifier, its insertion loss can be compensated.
