Gyaan about life in DSP class..
Not many teachers can do that-explain( and sometimes mock at) life to you using the subject they're supposed to teach.
So, Prof.Chetan Anand, one prof who can extrapolate DSP(Digital Signal Processing) concepts to life in different contexts, naturally turns out to be one prof I like and respect!
A few excerpts:
1.When explaining window functions: Life is like an infinite impulse response, but if you've to make sense out of it, you have to convert it to a finite impulse response, and for that you use the window technique. There are diff. types of windows, and depending on ur requirements, (window functions are specified by transition width, stopband attenuation of the filter etc), u choose. So the bottom line is, life has infinite options. Its your imagination, your thinking, which acts as a window to ur world. If u want a beach view, choose to have a window which gives u just tht from ur house! If u want something else, then choose the position( and shape and width etc) acc. to ur choice! If u can think big, imagine more(this is my extrapolation to his extrapolation), your life will have a greater value, you get to explore more!!( I like adventures,n exploring things is always an adventure(innit?), so I can't help but exclaim!-this is for those of u who find exclamatory marks sickening).
2.Symmetry property of an even function: Do good, you get back good things.Life is Symmetric.
3.When explaining overlap-save method where present output depends on a certain no. of previous inputs apart from the present input: Life's like that too. Your present output doesn't depend only on your present input, your past inputs count. Karmic theory I suppose.
One theory which I feel can work out as a win-win case for all of us. If this karmic theory speaks about our past inputs, we can start doing high activity that these actions itself are sufficient, and once they're done, its a thing of the past, and the theory hence favors us. Bottom line:Don't be idle.
I've given only a few examples, just so that you get an idea as to how to extrapolate your subjects(if studying) or work to life. We'll live a better life this way I think. Any extrapolations about ur subs or work or anything else I can't think of, that u can come up with, is to be conveyed thru comments! Kick-start ur imagination!
The end result: Any new concept I learn will automatically be extended to life. Any new concept which doesn't provide a funny enough or worthy extrapolation to life is not worth remembering(or it could probably be my limitation that I couldn't come up wid a good enough analogy and hence I don't realise the value of the concept)
This keeps me engaged in class, its fun to come up with extensions. You should try it too, if you even remotely match frequency with me(I remembered, there are a few ppl who say 'we match 'wavelength''-I wonder if I can match 'freq' with such ppl- though technically u will match :P)
P.S: If you're not an engg. student, u probably might not understand this post. My apologies.
Update: I think u can understand this post even if you are not an engg. student. You atleast get the basic idea, I think. Let me know thru comments.
