Transmission Flaws: Noise
• electromagnetic interference (EMI): waves emanating from electrical devices or cables
• radio frequency interference (RFI): electromagnetic interference caused by radiowaves
• Crosstalk: signal traveling on a wire or cable infringes on signal traveling over adjacent
wire or cable
• Certain amount of signal noise is unavoidable
• All forms of noise measured in decibels (dB).
