sonusman, he said sampling rate, but I did some research on digital voltage and found most of his advise suspect...I have to partially disagree with you about asking for advise in a forum. These forums have provided me with a wealth of knowledge to add to my own. True, there is no substitute for hands on experience in developing your skills as an engineer, but I don't see anything wrong with asking for directions. It would be bogus to take any info of any forum as indisputable law, but it definatley helps beginners, intermediates, or even advanced engineers, I think to have a place like this to collect info. For every hour I spend online, or in a book reading about engineering, I spend ten hours in my studio validating, disproving, and tweaking the info I get.
