  2. Outlines • 3-bit to 8-output Decoder • Truth table • Circuit • Lab

  3. 3-bit to 8-output Decoder • Decoder • Example：Taking attendance for demo • The process of mapping the ID number to the corresponding name 010

  4. 3-bit to 8-output Decoder • Truth table • 3 inputs 23(8) outputs

  5. 3-bit to 8-output Decoder • Logic circuit

  6. Lab • Build a 3-bit to 8-output decoder by AND, OR and Inverter • Use 8 LEDs to show different outcomes D1 D2 D0 D3 D4 D5 D6 D7 Please put the LEDs in line and use them to denote the outcomes in order

  7. Lab • Tip • Follow the step and construct these outcomes (X’Y’)Z’ (X’Y’)Z (X’Y)Z’ (X’Y)Z (XY’)Z’ (XY’)Z (XY)Z’ (XY)Z X Y Z X’ Y’ Z’ X’Y’ X’Y XY’ XY X Y Z

  8. Lab • You circuit should like this one
