simulate tempest with python

[ho3ynb]

Hi there,
I'm interested in this project. I wanna simulate that offline with python. Actually, I wanna read signals from a file and convert them to the monitor's image. I watched this video: https://youtu.be/k_vsFspGpAA, but I have some questions about DSP parts.
There are 5 blocks, "Hsync", "fine_sampling_synchronization", "framing", "normalize_flow", "sampling_synchronization". I would like to know what each block is used for, what are its inputs and outputs, and what its chain is? Are there other blocks as well?

Thank you
