1. The problem statement, all variables and given/known data
I'm working on a problem that implements the product of two 2-bit binary numbers (wx, yz) and produces such as the output. However, I am having a bit of confusion in regards to implementing the Karnaugh Map.

So this is what I have:
wx and yz can be 00, 01, 10, 11, the output can be either 0000, 0001, 0010, 0011, 0100, 0110, 1001

Would I simply make a sum of products for these outputs, then perhaps reduce it with the Karnaugh Map?

also keep in mind the output can be 0000 for essentially every other combination that does not make the output 0001, 0010, 0011, 0100, 0110, 1001

My question more or less comes down to this: how does one implement K-MAPS when the output is given with 4 bits?

Does the problem make more sense now, after our PM conversation?

### T.K

You need to make karnaugh map for each resultant bit using wx and yz.
Suppose R=0011
then R(3)=0 R(2)=0 R(1)=1 R(0)=1 .

This way you will get an equation for each bit in terms of w,x,y,z.
