WebHigh impedance<--->Ground. S2. Switches between supply and unconnected. In this switch the pin can connect to ground to output low (0). The other state is unconnected. If nothing is connected the pins float. Floating pins have an undefined value that oscillates between 0 and 1 with the noise from florescent lighting in the room. Web14 de jul. de 2024 · Add a comment. 1. Most oscilloscopes connect the signal ground to the AC power lead ground. That gives it another path to ground that in your case will presumably connect to the power supply AC input probably that path has more switching noise. To get a good trace on the scope you need a low resistance and low inductance …
