Spectrum of a 56k connection

[cobito]

If you have ever used a 56k modem to connect to the Internet, you probably remember the sound that the link negotiation made. In this video you can see a spectrum with respect to the time of the process

Mola!

The truth is that it is curious, and the sound has made me nostalgic xD

How good it looks when the carriers if in the race they had shown us this, surely more than one would have caught it much faster.

Not nostalgic at all, like we have to hear it again you see. haha

@kynes:

How good the wave forms look if in the course they had shown us this, surely more than one would have caught on much faster.

Used to seeing two-dimensional amplitude-time or amplitude-frequency graphs, the truth is that those representations where both the frequency spectrum and its evolution over time and the amplitudes of each band appear are very very illustrative.

Although after all that was behind it was much more lowtech than it seemed :troll:

My god what a déjà vu.
I did something similar back in 98, but with the sound of a tape for the amstrad (I transferred them from a radio cassette to wav format and the emulator (which I got years later) read it. The program I used to improve the sound offered a similar view, which was later repeated by a winamp plugin.
At 1000 and 2000 baud rates (they were my data, not programs).

Well yes, it causes a certain nostalgia. <:(

I hate that damn sound XD
