# Waveforms for a given ideal inverters circuit

I have the following circuit. All the inverters are ideal CMOS.

I need to draw the waveforms for each point (A, B, D, E, Vo), given that waveform at input.
What I want to ask is if what I did so far is correct?

Thank you for your time. (And sorry for the poor quality of the images)

Edit:

So, is this correct? (It is how I understood your response)

I'm not going to migrate it, as I think it is OK here, but this might have been better on http://electronics.stackexchange.com/. –  dmckee May 24 '11 at 0:28
