Tom,
You must have your brains fried :( You have no idea of System Engineering as
you would recognize that this is what the allured pages are talking about.
These pages speak about Power supply, Harmonic Filters , System Monitors
etc,etc ... in essence about an entire Amplifier. If you can not recognize
so much I wonder how you do your the job.
Have you seen much allusion to Helgi Grandberg or Motorola in Ameritron's
ALS-600 ?
Speaking about reliability and ALS-600 that blew up in my face once I turned
it on. Did _you_ design it ?
As far where the schematic come, it is part of the VHDL library included in
Xilinx. It is guarantied - and verified by us- that it works. I do not
believe that a TTL data book will depict the entire and functional schematic
of their technology even if it is this low level. This shows how little you
know and that your approach to engineering is in a cook book style. Take it
away and you're lost :(
But I do not believe you know what VHDL or Xilinx stands for :(
As far the relays et all. There are many ways to skin a cat. Once choses
what he seems to be more confortable with. And this is fine. But from a
question of how to implement something to your
inflamatory mesage is just to much.
What is it Tom, you feel somebody wants to take your throne ? A "coup
d'etat" ? Hi ... Hi... Hi ...
I'm am sick of your innuendo ... Just go away ... you are now in the
/null/device.
I hate mediocrity :(
Alex
===================================
If we can accept the notion that GUNS are
the killers and not the people, why is it that
we can not accept the idea that CARS are
the speeders and not the drivers?
Alex, trying to understand the world around.
