hi,
We have a plan to generate a digital audio signal that represents a 20 kHz analog sinewave, and encode this in SPDIF bi-phase protocol. We would like to generate this from a high speed DI/O card, connect this to the SPDIF IN on a M-Audio Delta 1010LT soundcard, and then use the resulting analog waveform from the soundcard (amplified) to modulate a set of current carrying coils. From my understanding the SPDIF format contains clock information, so that doing it this way allows us to (possibly!?) have a common clock for the audio and for other devices in the system, and avoid any timing problems using the sound VI's in LabView. Has anyone got any suggestions if this is possible, and if anything exists on using a DI/O card to generate digital audio/SPDIF and encode the clock signal?
Cheers,
Mark
