i need the truth table

find both of sop & pos

minimize both of sop & pos

find the cost of both sop & pos

4-bit inputs from the switches as a binary number and convert it to its corresponding excess-2 value if the input is even. Or to its corresponding excess-5 if it is odd. The input of the circuit will be x3 x2 x1 x0 and the output f4 f3 f2 f1 fo. Excess-2 means adding 2 to the input & excess-5 means adding 5 to the input Your design must include: 1. The truth table of the design 2. Finding SOP and POS. 3. Minimizing SOP and POS using truth table and Kmap 4. Finding the cost for both SOP and POS
