Hallo All ! i made a small program that can calculate the bandwidth of the magnitude in the fourier domain resulted from this mathematical formula: (V(t) = 1/(4*((pi)*a*t)**3/2) * exp(-(x**2+y**2 + z**2)/4*a*t) ) "Where x,y,z,a have particular values". Now i would like to illustrate the relation between this bandwidth and the time in waveform Graph. i mean a waveform graph that shows me how the bandwidth changes when the time changes for example from 0 to 200. So the time should be the x-achse and the bandwidth should be the y-achse. How can i do it? i attached my program. thanks in advance

Hey guys, i hope u can help me in this forum for my problem. i designed a small program which calculates the FFT of a time signal generated by a mathematical equation as it is shown in the attached file. My problem is that i urgently need to calculate the bandwidth of this FFT. How can i do it?? thanks
