1. Design a circuit with minimum logic that receives a single digit, coded BCD (4 wires) and as an output gives you the result multiplied by 5 – also BCD coded (8 wires).
  2. Due to the war in the land of Logicia there is a shortage of XOR gates. Unfortunately, the only logic gates available are two weird components called “X” and “Y”. The truth table of both components is presented below – Z represents a High-Z value on the output.Could you help the poor engineers of Logicia to build an XOR gate?
