How do you design bcd to 2421 code converter?

To design a BCD to 2421 code converter, first, create a truth table that defines the BCD (Binary-Coded Decimal) inputs (0000 to 1001) and their corresponding 2421 outputs. Next, derive the logic expressions for each output bit (D3, D2, D1, D0) using Karnaugh maps or Boolean algebra to simplify the equations. Implement these logic expressions using logic gates (AND, OR, NOT) to build the circuit. Finally, verify the design through simulation or testing to ensure correct functionality.
