diode,capacitor,Voltage src- question from interview

[darknessice]

I am an Electrical eng /Computer eng student,
I didn't "played" with this material for long time...
I hope the question would be clear, sorry for my bad english.
Ofcourse I could use spice etc. but I prefer asking you.

as far as I remember, the diode acts as a Voltage Rectifier (aka DC output)
What happens for diffrent types of Voltage src inputs?
Thank you

I think the answer they expect is that regardless of the waveform, the capacitor charges to the peak voltage of the input signal. That assumes the "ideal diode" has no forward voltage drop, if it has, the voltage will be the peak input minus the diode forward voltage.

as while as input voltage greater than diode forward voltage,capacitor will charge.
