Why TDM exists

Why TDM exists

Schematic of time-division multiplexing with three input channels entering a MUX, repeating C1 C2 C3 time slots on one high-speed line, and a DEMUX separating the stream back into three outputs

Modern links such as optical fibres have huge bandwidth, so it would be wasteful to dedicate a whole cable to one phone call or one data stream. Multiplexing lets many separate signals share one transmission path.

Step-by-step lessons on AQA A Level Physics Time-division multiplexing (A-level only). Each one builds up to exam-style questions. Physics is one of the most mathematically demanding A Levels -- at least 40% of the marks require maths skills at Level 2 (GCSE) standard or above, so build calculation and graph-handling fluency alongside the conceptual content from the start.
