Conclusion
The diode conducts while the current in the circuit is bigger than zero, in other words when the function
generator voltage is bigger than the one apllied to the DC source. For the diode to conduct the current must be
above zero. Therefore . If the dunction generator voltage drops below assigned reference
voltage the diode stops conducting and the output remains 6 volts.
In reverse biased, , where is the reference voltage and UVD is the voltage drop on diode.
In other words, the function generator voltage is smaller than the one applied to the DC source, then the diode
conducts
