Question for the super computer savy (OT),

[xxsk8er101xx]

"5) Given the algorithm for NRZ-I encoding, show the conversion of key bit-stream examples that help validate the algorithm (i.e. they test what NRZ-I addresses). (10 points)"

this is a question on my test. Does this make sense to you other computer savy guys?


Life is irrelivent and irrational.

I had to look this up to refresh my memory.

NRZI (Not Return to Zero Inverted) address bunches of 1's by encoding 1's as flops in signals. So 01110 would be 0 01011 assuming you signal started at 0, 1 10100 assuming you start at 1. So any stream with a lot of 1's in a row would validate the NRZI algorithm. Any stream with a lot of zeros in a row would invalidate the NRZI protocol. 4B/5B uses NRZI to encode 4 bit streams into 5 bit streams such that the stream never contains no more than three zeros in a row. It is only 80% efficient.

Complicated proofs are proofs of confusion.

int main()
{
cout << "Um............. yeah, what he said" << endl;
return 0;
}
there some comp code.

What if you had admin rights to life?

Let me correct my statement. Any stream with a bunch of zeros in a row would invalidate the algorithm. Any other stream is validated.

Complicated proofs are proofs of confusion.

ahh thanks!!!

man this stuff gives me a friggen headache! Why can't they friggen say it in english instead of ambiguous sentences?
