V. Lab Report 1. Explain why humans have a pulse. 2. Include a screenshot (image/picture) of the pulse signal you measured (voltage vs time). 3. Based on the figure shown in Question 2, use T2-T1 measurements to obtain the pulse rate (beats per second). 4. Using the built in functions, you obtained a plot of BPM vs time (see for example Figure T-T-L9). Include this plot in your report and compare the values there to the pulse rate you obtained in Question 3. Are they similar or different? Why? 5. Include a figure showing pulse integral. Explain what this shows. Requirements/Questions:
