    Graduate Inverse FFT how to scale the x-axis

    Thanks very much! You were right! It was a problem with measuring the Pulse-width and additionally the input signal into the iFFT wasn't in Hz. I'm really happy that this is working now, thanks again for the good advice!

    Graduate Inverse FFT how to scale the x-axis

    X[k] = X_{\mathrm{s}} \left( \ \frac{k}{N} \ F_{\mathrm{s}} \ \right) What exactly is this Fs in the frequency Domain? Is it the differnce between the ending and starting frequency in my Gaussian-Pulse-Plot? If not that might be the mistake

    Graduate Inverse FFT how to scale the x-axis

    Ok I definitely tried that one out, but the Gaussian-Pulse was too narrow! I tried a few different factors and came to the conclusion that the above mentioned factor multiplied with 4.41 gives the best results. But I don't have an explanation for that one. By the way Thank You for replying!

    Graduate Inverse FFT how to scale the x-axis

    Hello I have a Gaussian Pulse in the frequency domain and transform it with the IFFT into the time-domain. My Problem is now that I can't figure out a way to give the sample points the correct time-scale. What kind of formula do I need to use? Thank You for helping me!
