There
are four combinations of diode states that can occur in this circuit.
Let us examine all four possibilities. Here are the four combinations
with each diode replaced by either a short circuit or an open circuit,
depending upon whether we assume the diode is ON or OFF
It's just a diode and a resistor operating on an input voltage. We would like to determine how the output voltage depends upon the input voltage. We know something about the circuit. When the diode is ON, the voltage across it is zero because it acts like a short circuit. When the diode is OFF, the current through it is zero because it acts like an open circuit. We have one or the other of these two situations. It can't be both ways, and it has to be one or the other. That gives us a strategy that will let use figure out what happens in circuits with diodes.
We can start to figure out what happens in this circuit by examining what happens in the circuit in the two situations.
