Hello,It seems thaat we multyply the F- axres by T in order to convert to DTFT bu then i cant see how we get PI in the place of where FS was in CTFT
Fs*(2*pi)/FS =2Pi
but i cant see.
so i dont know what is the factor we multiply to get the converstion of CTFT and DTFT?
Thanks.

Update:
i understood it from the good manual bellow
