There is *always* a need to make the math easier if I’m quickly typing up an example. For proof I reference the hundreds of posts in the archives where I didn’t quite get it right :) Indeed, the real numbers could be just about anything. They are highly dependent on what’s in the specific module. In some cases, the clock involved is well over 300 MHz. Bob > > Thanks for the "hanging bridge" explanation.
