Physical Layer Propagation: Transcript

Chapter 3 Updated January 2009 Raymond Pankos Business Data Networks and Telecommunications 7th edition May only be used by adopters of the book 3 2 31 Signal and Propagation A signal is a disturbance in the media that propagates travels down the transmission medium to the receiver. brPage 1br DataLink Layer 1 DataLink Layer 2 DataLink Layer 3 DataLink Layer 4 DataLink Layer 5 DataLink Layer 6 brPage 2br DataLink Layer 7 DataLink Layer 8 DataLink Layer 9 DataLink Laye Cost function.
