| Apr 18, 2023 at 22:55 | comment | added | Dan Boschen | @Apinorr Thanks for letting me know. There might be a lot more background detail needed than I can fit in a simple StackExchange post. If you're really interested in this stuff, I routinely teach basic DSP courses through the IEEE and dsprelated.com. The "DSP for Wireless Communications" will get you totally up to speed in the FFT as well as filter design. You can find links to those in my profile as this course is coming up in June! | |
| Apr 18, 2023 at 14:00 | comment | added | Apinorr | So i did this and this works ! I must say I don't really understand why even if your answer is very long, I think I need a bit of time to understand this... | |

| Apr 14, 2023 at 12:42 | comment | added | Apinorr | Also, why is the amplitude of the field not correct in the recovered sine signal ? | |

I tried to replace time_range with the time that you gave above (replacing fs=18.02GHz) but it doesn't change the frequency of the signal that I obtained with the inverse Fourier transformation.. Also, I don't really understand your answer... Could you maybe explain it more or with more simple terms? :/

| Apr 14, 2023 at 12:09 | comment | added | JRE | "OP" = "original post" - that's your question. "DC" = "direct current" - that's the frequency bin of the FFT corresponding to a frequency of 0 Hz. In electronics terms, "0 Hz" is direct current (DC.) | |
| Apr 14, 2023 at 12:01 | comment | added | Apinorr | Thank you for your answer, what do OP and DC mean here ? | |
