Homework Equations
Nothing which applies, I think.
The Attempt at a Solution
The answer has already been provided. I just have a concept question.
The full rectifier circuit is active only where the input voltage is 4 or greater (marked in blue). But why 4?
Is it simply the sum of the 4 diode's threshold voltages (marked in red), that is, 1+1+1+1=4?
But only 2 diodes are active at a time (at each peak or valley of the input wave), right? So, why isn't it 1+1=2 instead?
Or am I on the wrong track entirely?
