If you are going to > use this to "protect" your amp it has to be virtually failsafe. Trust not protection to a software implementation on a PC. If you're really worried about overdriving an amplifier, then you need a hardware input limiter of some sort. There's just too many things that can go wrong in the PC environment (oops, it just hung, my protection loop froze..). Remember that the dttsp core has to get an input from the ALC signal, and then go in and adjust the gain, which then changes the levels of the signals emerging from the DAC. Software is ok for this kind of thing, but you want it running in a dedicated processor (e.g. That PIC). _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/ _______________________________________________ FlexRadio Systems Mailing List FlexRadio@flex-radio.biz http://mail.flex-radio.biz/mailman/listinfo/flexradio_flex-radio.biz Archives: http://www.mail-archive.com/flexradio%40flex-radio.biz/ Knowledge Base: http://kb.flex-radio.com/ Homepage: http://www.flex-radio.com/
