What's your favorite linear transform /sci/? Mine is the Fourier Transform.

>> No.10115422

Literally why would anyone go with Fourier instead of Laplace, it's the same shit but even better

>i love the fourier transfirm because it can be used in my spectroscopy

hell yeah, fourier transform FTW. love the QM reference in your pic related too OP, noyce

scalar multiple is best linear transform

Why?

>>10115422
as an engifag I approve. I guess Laplace works best with causal signals and the evaluation of the integral works out differently.
Laplace is god tier for controls engineering, Furry-er is more like making the work look fancier to impress brainlets. Haven't seen control design in fourier domain to this day

how about this one, i called it the dirac transform

[math]f_D(k) = \int_{-\infty}^{\infty} dx f(x) \delta(x - k)[/math]

i find it general and powerful
