Code Conversion

The method or technique used to convert code from one format to another is termed code conversion. Code conversions are most commonly used in computers, digital electronics, microprocessors, etc.

Question

An example of an encoder is an outpòt device (çafled 7-segment display) that
displays a decimal digit encoded in BCD format. The input to this encoder is the 4-
bit number A3A2A;Ao and the outputs are the line segments L1, L2, ..., L7. The digit
is displayed by "turning on" a subset of the line segments. For example, when all
seven segments are on, the output digit is 8, whereas when all lines except L2 are
LI
LA
L6
L2
LS
L7
turned on, the output digit is 0. Construct a truth table from which you could build
this encoder. Derive the Boolean functions of L1 and 2. Don't draw the circuit.
