- Connect wires from A00 and AO1 to AI0+ and AI1+ (Disconnect the Function Generator output). Make sure that the Prototyping Power is on. Modify your vi to collect samples from both AI0 and AI1. Then open DelayedChirp2DAC.vi and run this vi. Zoom in in the time and frequency domain to examine the waveforms in detail. Describe in detail what you see. Measure the difference in time between both channels. Hint: Start and stop your Data Acquisition vi until the entire signal is in the middle of the buffer.
- Plot the Cross Correlation of the 2 channels and see if the peak is shifted from the middle, the number of samples you measured from the previous step.
- Task 6 - 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?
