That is nowhere near the same as summing periodic square waves.

I'm just asking you to corroborate statements you have made which, in my ignorance, I consider to be bogus hand-waving. Nothing about you there. Just the information you are promoting. I don't normally deal in innuendo and personal attacks. Though I do occasionally get irritated by what I perceive to be hogwash. People who know me will tell you, if I am wrong I will happily admit it. regards Steve -- Steve Holden +1 571 484 6266 +1 800 494 3119 PyCon is coming!
