Inter Symbol Interference

Open Up Your Eye Diagrams!

Debut

First things first: a quick introduction to our title. ISI is a communications phenomenon where the electromagnetic pulses you send smear into each other thanks to an echo or two. If only you'd slow down, your bits would make it through just fine. But if you recklessly spout off at the speed of your own thoughts, the echo from info-carrying symbol N winds up being received at the same time as info-carrying symbol N + 1, and you've prevented effective communication of your own signal. SO. Take the time to make sure our arguments and inquiries are thorough, well-posed, and understood. I really doubt we will actually do so here, and thus our title.

I'll be posting here as Louie Fakes instead of my real name, because the internet, she never forgets. I'd like to avoid taking any kind of responsibility for my comments! This blog is going to be a back-and-forth between myself and my buddy. We're both recent graduates of the University of Virginia. I've gone West to pursue a graduate degree in electrical engineering, and my boy's held it down back East working nine-to-five doing web design for a popular domain name registrar.

I'll throw out a couple of potential topics for our virgin diablogue, and let him pick which one we go with. I'm confident we'll run through them all soon enough! In an unbiased, alphabetical ordering:
  • Bankruptcy
  • Credentialism
  • Infidelity
  • Net Neutrality
  • Patriarchy in the Internet Age
  • Vegetarianism/Veganism
Over to you, my good sir!
