So I am enrolled into this course.(adsbygoogle = window.adsbygoogle || []).push({});

And we are learning probability and statistics and all that good stuff.

But one thing bothers me VERY much.

I lie, a lot of things bother me about this course but here is the first one:

Transformation of random variables.

So far we have been only doing that pure, raw unattractive math. And I cannot swallow the point of that.

Says here in the book, you have a voltage in input and you get something else out...

But still I cannot wrap my head around it.

How does this apply to communications!?!??! This transformation of random variable?!

LTI systems I understand. But we get precise inputs and precise outputs. What role does a random variable take in my learning?!
