Need to confirm equation for this circuit

[AARRGGHHH]

This circuit is named ((AB)' + (CD)'). However, isn't the correct equation ((AB)' + (CD)')[b]'[/b] ? Comments are invited, I'd like to get a consensus on this.

Thank you

Hi AARRGGHHH,

I believe [code] ((AB)' + (CD)')' [/code] is the correct equation for this.

Enjoy your logic fundamentals

Oops, think you are right.
It looks like ((AB)' + (CD)')' to me.
