Two kinds of SAWF using respectively usual and SPUDT tapered transducers with 15% fractional bandwidth are designed on Y128. One transducer is block weighted, and the other one withdrawal - weighted.
我们在Y128基片上采用一般型和SPUDT型锥型换能器制作了相对带宽约15%的声表面波滤波器，一个换能器采用“块加权”，另一个换能器采用抽指加权。
Firstly, the force metro bogie four wheels weighted are analysed, because it have a big impact on metro bogie performance, and the weight transducer circuit is designed.
首先对转向架性能影响较大的四轮称重参数进行分析，设计了精度较高的称重测力变送器电路。
