                      浅析单向方波和双向方波的区别


                      在前面的介绍中我们知道北京11选5走势图果,电磁式无源蜂鸣器的驱动信号是单向方波(比如5Vo-p)北京11选5走势图果,而压电式无源蜂鸣器的驱动信号为双向方波(比如5Vp-p)北京11选5走势图果北京11选5走势图果,那单向方波和双向方波到底是什么区别呢北京11选5走势图果?我们用图形直观的演示一下:


                      双向方波为同时带有正负两个方向的方波信号北京11选5走势图果,如下图所示:


                      单向方波是只有正方向的半个周期的方波信号,如下图所示:


                      以上为一般电磁式无源蜂鸣器压电式无源蜂鸣器的推荐信号北京11选5走势图果,当然不是说完全不能互用,只是会影响到产品本身的性能指标北京11选5走势图果。
