fourier transform integration problem
The problem is t(x)=I(0)exp(-a(x)) which is also roughly equal to =I(0)[1-a(x)] but what if we have s(x)=t(xo-m*cos(wt))
find the fourier transform of s(x):
which is given by:
S(y)= int(s(x)*exp(-i*x*y))dx
= int(t(xo-m*cos(wt)*exp(-i*xo*y))dxo
and now is where i get lost the next line in the solution is:
= exp(-i*m*y*cos(wt))*int(t(xo)*exp(-i*xo*y))dxo
i dont understand how they took out the mcos(wt) from the integration, can someone help giving me direction to get to this line before continuing
Re: fourier transform integration problem
Your post is difficult to read. Can you rewrite it using Latex?
Re: fourier transform integration problem
![t(x)=I(0)e^-^a^(^x^) =I(0)[1-a(x)]](http://latex.codecogs.com/png.latex? t(x)=I(0)e^-^a^(^x^) =I(0)[1-a(x)])
we have we have =t(xo-mcos(wt)) )
fourier transform
e^-^i^x^y dx =\int t(xo-mcos(wt))e^-^i^x^o^y dxo )
e^-^i^x^o^y dxo )
this is the line i am lost line ,i dont understand how they took out the mcos(wt) from the integration, can someone help giving me direction to get to this line before continuing
