I'm confused as to how I can check why the diodes are non-conducting/cut off when vi is postive. (See figure)
For the diodes to be cut off the voltage across the diodes must be negative.
I don't see how I can check this.
I'm looking at the first diode and trying to find vd1, and it looks like the voltage across it is,
\(v_{D1} = \text{floating voltage?} - v_{I} \)
Can someone clarify this for me?
