Line Coding Schemes: NRZ, RZ, Manchester and AMI
Bits are just ideas until they become voltages — line coding draws them in a way the receiver's clock can follow.
What this unit covers
Unit 4: Bit Synchronisation, Line Coding and Multiplexing
- 1 Bit Synchronisation at the Physical LayerCounting silence is hard: a receiver that loses the beat for a single bit garbles everything that follows. · 7 min
- 2 Line Coding Schemes: NRZ, RZ, Manchester and AMIBits are just ideas until they become voltages — line coding draws them in a way the receiver's clock can follow. · 10 min
- 3 Asynchronous and Synchronous TransmissionSend each byte with its own start and stop, or march whole blocks in lockstep — two ways to keep both ends in time. · 4 min
- 4 Multiplexing and Switching TechniquesHow do dozens of radio stations, calls and downloads share one link without tripping over each other? · 5 min
