Hello, I am new to electronic design but I am learning as much as I can.
I need to make a circuit that has 2 lanes, lets say 1 lane is a -30v DC and the other lane is 150v DC with an AC sine wave attached.
I want to make a circuit that will switch the output to the -30v DC lane when there is no AC signal and then switch back when the AC is applied.
Maintaining signal purity is important for the 150vDC/AC lane so having it go though anything other than a lowish value resistor is not preferable.
Can this be done?
