Median Filter is the simplest way to remove random noise from input signal. More about it you can read at http://en.wikipedia.org/wiki/Median_filter
Using the info from the previous Week #44 Challenge make Median Filter and experiment with different window sizes to filter the raw ECG info and to see how it changes the shape of the signal and the measurements of the pulse rate.
You can code the solution in any programming language during the weekend and have to submit it to firstname.lastname@example.org latest on Sunday March 9th.
On Monday we will upload the solutions on GitHub https://github.com/OLIMEX/WPC
You can play with your real name or with nick if you want to be anonymous, we will not disclosure your personal info if you do not want to.
