Notes:

1) Relationship between file names and labels in Figure 2 of Problem Set 3 
File Names           Figure 2 Labels
GoodPPG            	yo
CorruptedPPG       	y
noise_reference    	a  

2) There is one GoodPPG reference signal that can be used to compare your      
recovered signals, z, with for both data sets. 

3) One of the data sets is tricky. Can you explain why you are getting strange results? 

4) How do you think you should choose the filter order?

GoodPPG.txt

Data set 1 contains the following files:
