... Fourier Smpling Complex has been doctored /repaired.
Please, recycle the prevous work sheet "Fourier Sampling complex [Scarp]"
Observe the definition of 'i' imaginary in the program.

... finally, the "i" imaginary does not have to be included in the program.
I have just checked "ifft" padding 0's: works great, here is proof/application.
Something wrong with "Phase_mod_pi".
