  1. Time Division Multiplexing

  2. TDM • Time division multiplexing is used widely in modern communication systems • TDM can handle analog or digital data • Analog continuously varying signals • Digital logic values 0 or 1

  3. TDM • Components of TDM system • Selector, Counter • Decoder and Latch • Gate AND digital • Draw diagram 2 channel device • Transmission gate analog

  4. TDM • Reduces number of wires required • Data, Reset, Clock, Gnd • Data channels 2**n • Example 8 bits • Channels 2**8 = 256 • Scan rate is normally very rapid

  5. TDM • Diagram of a 4 channels system • Diagram of a digital latch or memory device
