Two separate recordings of equal length are made of a periodic pulse train being transmitted down a noisy channel. The following table shows the recorded values of the sampled voltages. Determine the amount of lag between the two recordings and the period of the waveform. You can use MATLAB for this problem. Use Cross-correlation (or any other technique) to get your answer. 

Attach the plots (graphs). 

Record 1: 6.02-5.987.92-7.96-0.78-8.349.22-2.65-3.79.51 5.533.5-3.18-8.858.211.69-0.066.65-8.00-9.21 -0.787.27-5.98-3.979.114.232.99-1.85-5.273.81 6.62-2.642.08-5.91-3.58-1.653.64-8.19-3.504.84 7.252.93-4.42-8.213.61
