thank you very much

Dear Prof. Jason Gallicchio, your lectures are excellent and can teach any student in the world the principles of communication and the use of GNU Radio and SDR.
I am going through them now and they are simply better than any theoretical course taught in the academy. Your course illustrates the principles of communication to the student.
And now I now I wanted to ask you a question regrading this lecture (SDR 15): why does the spectrum appear smooth when the source is deterministic, while when the source is random you see a noisy spectrum? After all, you are not adding white noise to the system. Can I understand that this noisy spectrum emerges due to spectral calculation of random signals of GNU. Every time GNU calculates spectrum, it has partially different signals in the pipeline, so that's why we see these small fluctuations in the spectrum and a not because of digital quantization problems in the calculation?
