Been mulling WM over and recollections of what he posted and things I read 
in the late 70's early 80's on analog design...

So, a triangle wave generator, WMWMWMWMWMWMW....

A flip-flop circuit or two with divider so that after a couple of cycles, a 
blanking interval is created for a half cycle, two more cycles, then a 
blanking interval, et cetera...

You'd get W||M||W||M||W||M||W where || is the blanking interval triggered by 
the leading edge of every two cycles.

>From what I recall, this is what he did, or at least mentioned.  I also 
recall some mention of doing it purely with timing as I mentioned early and 
seem to recall some issues with that if the synch was off.  Wasn't there 
some captures posted through the group with blanks in odd places, such as 
the middle of the W and M?
