Enlightenment

The meeting with my supervisor yesterday was almost confusing. For all my engineering career I've been told that we need to know how to get things to work (ie: which equations to use) but not why it works (ie: what those equations actually mean). Yesterday my dream has been shattered when my supervisor told me it's not enough to know what the equations do. I am to write the equations out and think about it and meditate until I've reached enlightenment and can actually tell him what all the terms in the equations does and how it affect the signal.

The most inportant equation (written on my white board at the moment) involve a triple integral over a formula which has 3 different variables that stands for time (and 2 for frequency, but that I can haddle.)

ARGH!

**WARNING: mindless conversation to self to follow. It WILL involve signal processing. You have been warned.

Okay. Calm down Lisa. Look at the equation. It's like a Fourier transofrm over the ambiguity fuction, and added the kernel... okay why the HECK is there an u as well?? I thought t and tau took care of time... where did u come from? Calm down... step at a time... what the fuck does the ambiguity function MEAN?? Ok... slow down... watch your breathing... look deep into the symbols... now. Visualise the signal and see the function dissolving the signal into it's time and frequency components... just like Fourier transform... but in time as well... now look at the ambiguity functions... ok I'm lost...

/back to the search of enlightenment.
