It would be nice to measure the FFT of a signal in CircuitLab. I would also like to see Total Harmonic Distortion.

Yes, this would be nice

3rd this. For those working on audio circuits -deliberate distortion profiles (fuzz and overdrive stomp boxes), and low distortion devices (mic pre-amps) - FFT analysis would be very useful and very used. Thanks!

I would also like to see this. Thanks

Also for modulation circuits this would be a neat feature

Yes FFT would be very nice!! I'm using circuit lab for a lot of basic principle circuits in my communications systems course, but the lack of ability to show the spectrum of a signal definitely holds me back.

Completely. Please can we have this? I'm modelling various saturation / clipping approaches and spectral analysis is a must...

FFT would be very usefull!

Definitely! FFT would be very nice.

How do we find out the status of this feature request? Will a circuitlab employee comment?

Thanks, Lewis.

11 years later and still no FFT implemented. This can't be that difficult. Please CircuitLab, we need this FFT feature!
