help with some electrical engineering (fourier transforms)

[mchammer187]

For a square-wave audio signal of 10 kHz, what fraction of the available energy is percieved by an average adult listenber of age 40 whose hearing extends to only 16 kHz?

i dont know if you need these at all

T = period

P=1/T * intergral of (v^2 / R) dt from 0 to T

v(t) = 4 V / Pi * ((sin (w0 * t) + 1/3 * sin (3w0 * t) + 1/5 * sin 5 (w0 *t) +...))

BTW the answer = 81%

it's t= acrctan (frequency) integral dy/dx rt.a^2-x^2

then use 1/4 IM[3/4-2x]

Real[3/4]

can you elaborate a little more

V=IR

wait, I am supposed to learn more than that? 😱

hey superfluous, did aravena teach you that?

 

[superfluousmonkeys]

I was just pulling your chain dude sorry 😉 That's some tidbits from my 1552 HW 🙂

Aravena? Heard of em. Nope I got rioux, he's cool.


Good job on ohm's law though....

superfluousmonkeys,

you in EE at LSU? what classes are you in?


btw, you should enable your private messages

I'm in EE, I'm in calc 1552 - poli 1001 - phil 1000 - econ 2010 (Soon to earn a "W" in 😉 - and CSC 1253 spekaing of that I gotta type up some pseudocode.
