Roommate: Filter it, would you please? (* Was talking about the tea*).

Me: Alright buddy, say no more. (*Names the signal that I was working on as "Tea".*)

(*Got the filtered output 😎*)

I had my presentation early morning, it was 3am, and I was still up because the code was not compiling. Then showed up my roommate who had gone for party. Can't believe that he was the one, in the half drunk state, was able to find just a short typo,but not ME, EVEN THOUGH I HAD 3 CUPS OF COFFEE the same night. Lesson learned. Patience is a virtue. Blessed to have a nice roommate. :)
PS. It was a Matlab code for filtering the mentioned portion of an ECG Signal, and analysing the problem faced by the patient. Well, I was pretty sure to get arrhythmia if I couldn't complete the code by morning.
