TESTE DEIN WISSEN

The symbol acceptance radius is a deciding factor for the symbol error probability. However, 1 the bit error probability also depends on the encoding of the symbols. The symbol-encoding in Figure 2.4 is not optimal because multiple bits can flip when neighboring symbols are mixed up due to signal noise. Which kind of encoding could help to solve this problem?

Gray-codes with a Hamming distance of 1 between neighboring symbols would solve this problem.

How does a twisted pair cable help against interferences from external sources?


Lösung anzeigen
TESTE DEIN WISSEN

Interferences affect both signal lines at the same time. When a differential signal is sent, the receiver can reconstruct the original signal by subtracting the signals from each other. Any interferences are canceled out

TESTE DEIN WISSEN

Is using a twisted pair cable more beneficial against interferences of small sources close to the wire or ones that are farther away? Explain your answer.


Lösung anzeigen
TESTE DEIN WISSEN

Better against sources farther away. The interferences close to the wire affect the closer wire stronger than the one on the other side. The interference is therefore different. With longer distances, the interferences should even out.
