Study Day 5: Part 2

finished cognitive.


now, arranging these signal notes... i have to study signals.
the hardest subject this semester... T.T


Poh's parts are much more difficult...
i still confuse bout convolution and correlation

i mean, he's not consistent in giving the correlation examples. i think (as i've read in his notes) that i should have shifted the f(x+n) to the RIGHT, then shifting continuously to the left (increasing positively).

however, in his example and tutorial (that counts 2 so far), he shifted it to the LEFT just as convolution... but without flipping it with respect to the x-axis... then shifting continuously to the right (however, the main n value is NEGATIVE)


damn, i'm so confused... T.T

let us start in 6 minutes...
