当静磁表面波器件的输入换能器的导条包络按照小波函数的包络设计时,静磁表面波器件的输入换能器的脉冲响应函数等于小波函数,从而制作出了静磁表面波式单尺度的小波变换处理器.首先,根据小波的包络函数,定义出了导条长度函数,然后,从该导条长度函数可以计算出输入换能器的各导条长度,最后,根据导条长度及导条宽度设计出输入换能器,从而实现了输入换能器的导条包络按照小波函数的包络设计目的.本文也给出了静磁表面波式单尺的小波变换处理器的插入损耗的补偿方法.当静磁表面波式单尺的小波变换处理器的输出端联接到放大器时,它的插入损耗能被补偿.
When the envelope of the input transducer of the magnetostatic surface wave device is designed according to the envelope of the wavelet function, the impulse response function of the input transducer of the magnetostatic surface wave device is equal to the wavelet function to produce the magnetostatic surface Wavelet single-scale wavelet transform processor.First of all, according to the envelope function of the wavelet, the length of the bar is defined, and then the length of each bar of the input transducer can be calculated from the length of the bar.Finally, According to the length of the bar and the width of the bar, the input transducer is designed, so that the envelope of the bar of the input transducer is designed according to the envelope function of the wavelet function.In this paper, A method of compensating insertion loss of a transform processor When the output of a magnetostatic surface wave type one-foot-band wavelet transform processor is coupled to an amplifier, its insertion loss can be compensated.
