I need a solution to this problem question so i can understand it. I suspect the solution makes use of XOR. The figure is just 7 segments making an 8 symbol.
The figure above shows a 7 segment display often used in electronic circuits. Each segment consists
of a light emitting diode (LED) which may be turned on independantly of all the other segments.
The segments are designated letters as shown. To display numbers on the device the correct display
segments must be turned on.
The display is to be used as the digits in an electronic speedometer in the latest Holden. Four wires
(labelled A, B, C, D where A is the msb) carry a 4 bit BCD from the cars computer to each
display. To convert from the 4 bit BCD we require a BCD to 7 segment circuit. Design the logic
circuit required for each segment.
