Hi everybody, I have a simple question. I am using the DSK6711 which has an AD535 on board. The AD535 has the sampling frequency limited to 8 Khz. Does this also mean that i will be unable to play out audio through the ad535 at a higher frequency, or is it just that the input analog signal will be sampled only at 8 Khz? Thanks and regards -Sunil
