Hi All,
In my project I'm driving a piezo buzzer by CPLD.
One side of it is connected to a square wave at 3.3v, and the other side is connected to an opposite square wave. in such way I get a higher sound volume, because, relatively to the buzzer it's operate at 6.6v.
My question is why I see overshoots on the signal when I measure by oscilloscope? Is it real overshoots or it's fake by the measurement device?How can I be sure?
Thanks
