No i dont think soo, because the saw is twice the 
frequency of the square!

But another interesting thing is the clean and nice PWM
you gett when driving the saw thru the xor gate.

And another interesting thing is the "fixed" frequency
and the "second" phase pulse pointing of the xor gate
when you are sending the saw to both of the xor gate
input pins.

If yo do so then you get a short output pulse at pin 1 (i think)
at the frequency of the saw and as you warying the
PW (dc shift) of the saw there appers another short pulse
in the pulse train.This pulse moves from ether side of
the stable pulse trains outher limits.

(Ooh dear, what this was difficult for me to explain!!!)

I have no idea on what one would use this for!!:)

Plashe plonting plotter plablpthpthpfftp!!!
