Hi TideMan,

Great post. At the beginning of your expressions for each domain, what exactly is the term '3D':

w=3D2*pi*(0:N/2-1)/(N*dt)

Many thanks,

Sina

Hello,
I've a 2D DFT problem which I could not manage to solve. Can anybody help me find the wave number in the plot of spatial spectrum?
The problem is described in the following link https://dsp.stackexchange.com/questions/82903/what-is-going-wrong-with-the-plot-of-2d-spatial-spectrum-at-a-specific-frequency?noredirect=1#comment174526_82903
Thanks and regrads,
S. Alam
