weird graph again lol

because im good at doing something unnecessary, last time is pspice, now with matlab >:D

actual signal, plan to do some band-pass filtering, so the actual output should be another periodic signal..

result I : the signal spray like a shotgun bullet, shouldnt be that much lines

result II: star at far far galaxy explode beautifully, so does my result graph

result III: .... bird eye view of a stealth fighter????????????? heck aerotechnology is not what im studying

it's a troublesome homework, thanks to that, i have to sleep late at 3, in the afternoon.

. . . maybe i should go for an art degree instead of engineering one? :0
