1、PGA460手册中7.3.9.1 Time Decoupling ：
The transducer is less exposed to noise generated by the driving circuit during this process and is less loaded,
meaning the detected echo is capable of producing a higher voltage swing to be detected by the PGA460-Q1 device.
文档中描述使用DECPL_的目的是减小驱动电路带来的干扰，以及可以得到更高的回波信号。是否理解正确？
2、从干扰与增强回波信号上来讲，有详细的实验数据支持吗？对比能提高多少信噪比？
/3、PGA460手册8.2.2 Direct-Driven Method
该驱动方法可以使用于PGA450设计中吗？
