I added the newest version of the temperature sensors lecture.

For HW #9, don’t worry about the heartbeat sampling rate. That question need to be reworked- using Nyquist Theorem, the correct answer would be found by:

Assume 200 beats per minute is the fastest heart rate you’d find and convert that to a frequency

200 beats/min * min/60s = 3.33 Hz.

Apply Nyquist Theorem:

3.33 Hz * 2 = 6.67 Hz is the minimum sampling frequency, not 400 Hz.

One junior design group this semester is learning that real heart beat measurements are more complicated, but 6.67 Hz is the minimum sampling rate per Nyquist Theorem.
