Create a truth table and then use a Karnaugh map to produce the MSOP equations for an Excess$-1-$to$-$BCD Code Converter. The converter should take an Excess$-1$ number, ABCD, and convert it to it's BCD equivalent, WXYZ$.$ For this problem, only find the equation for the output X$.$

To create an "Excess$-1"$ binary code value, you simply add one to the binary number.

e$.$g$.0010-->0011$
