声表面波式小波反变换器件温度补偿

wo wavelet transform devices of surface acoustic wave (SAW) type are used to manufacture a wavelet inverse-transform device of SAW type. Because the center frequency of wavelet transform devices of SAW type varies with temperature, the wavelet inverse-transform device of SAW type is subjected to temperature compensation. The temperature coefficient of the first wavelet transform devices of SAW type is opposite to the one of the second wavelet transform devices of SAW type, so that temperature of wavelet inverse-transform device of SAW type is compensated. This paper also discusses in detail the design, production and experiment for the wavelet transform device of SAW type.
