Even with my electrical engineering degree, four years of hard math, signals courses and understanding all of this at an abstract level, it all seems magical to me when it works in practice.
Thanks to all the tireless engineering of all the folks that manage to abstract this all away so we get clean zeroes and ones at the other end.
I'm definitely a digital, logical, bits-type-of-guy.
- sour-taste 2y agoI certainly don't have your credentials but wasn't the point of the articles that it looked flashy while proving nothing about the capabilities of the chip?
- treflop 2y agoPretty much. If you took undergraduate EE, you would learn most of how to pull off Broadcom's trick when you learned transmission lines: https://en.wikipedia.org/wiki/Transmission_line https://en.wikipedia.org/wiki/Transmission_line Cool applications, but probably one of the more boring chapters IMO...

- cushychicken 2y agoOne of the fun parts of this is when you start realizing digital methods of improving analog signaling exist. He mentions one of these techniques briefly in this article: equalization. The condensed version is that you use an ADC for the receiver, sample the incoming waveform, then pass the resulting samples through a digital filter that amplifies the high frequencies and suppresses the lower frequencies. This is actually quite good at counteracting the losses and phase shakeups that come with passing high speed signals through long cables.
