How to create FFT from CSV file?
显示 更早的评论
Hello, I have a large csv file containing lots of data. In the x-axis, time (0 to 30ns) and in the y-axis, current values. I want to create a frequency spectrum of my data (specifically: current). I can plot the signal. But couldn't succeed to create the FFT. My frequency spectrum should be from 0 to 10GHz. Can Anyone help me with that?

Piash - can you attach your csv file and show the code that you are using to perform the FFT?

Yes. Cause, appear be some error in the read or fft routine that you are using.
