互补序列在声表面波换能器编码和红外线光谱测定中也有应用。
The complementary series also find its applications in the acoustic surface, -wave transducer coding and the infrared spectrometry.
梳状换能器可看成若干叉指单元电端并联，声端首尾串联而成的网络，采用单向结构可降低采用这种结构的声表面波延迟线的损耗。
The comb transducer can be considered as the network of the parallel connection of some units of IDT electrical ports and the series connection of their acoustic ports.
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。
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.
