anonymous · Answer

fourier transform stuff?

anonymous · Answer

Yes 2 pulses right?

anonymous · Answer

sinc will turn into rect  , sin will be a delta , speaking roughly

anonymous · Answer

them I have 2 functions, 1 centered in -PI/2  and 2 pi/2, If I calculate these areas, will be the energy? I don`t know if I'm too lost..... my first Parseval hahah

anonymous · Answer

convolve the two , then you go on to find energy

anonymous · Answer

are you electrical engineering student , btw?

anonymous · Answer

Telecomunications

anonymous · Answer

this is discreet inverse fourier transform ,I need to some review on this too

anonymous · Answer

If I have the two pulses of equal size, compute the integral is equivalent to computing the area of these pulses. Then with Parseval, my result for the energy is pi / 2 * 10 ^ 3
