** Task 3 - Connect wires from A00 and AO1 to AI0 and AI1 (Disconnect the Function Generator output). Modify your vi to collect samples from both AI0 and AI1. Then run [[media:DelayedChirp2DAC.zip|DelayedChirp2DAC.vi]]. Zoom in in the time and frequency domain to examine the waveforms in detail. Describe in detail what you see. Hint: Start and stop your Data Acquisition vi until the entire signal is in the middle of the buffer.

*** Task 4 - Finish exercise
** Task 4 - Using the 4 microphone array and the metal data acquistion box, collect samples from all 4 channels and display them on your graph. Measure the delay between the signals - does it agree with the speed of sound?
