Testing Digital Audio Using NI X Series Multifunction DAQ

[Todd S.]

Description	Products Used
With X Series Multifunction DAQ devices, you can perform hardware-timed digital I/O at up to 10 MHz with a new digital timing engine. In this demonstration, we are acquiring a digital input stream of S/PDIF audio with our DAQ device. We then decode, modify, and reencode the audio stream and send it to a receiver, which then outputs analog signals to the speakers. We then test these signals with the simultaneous sampling analog inputs on our X Series device.
