Simple Digital Circuits Problem

Any bored electrical engineering students who want 50 easy credits? =P

I need the equations for a 3-bit gray code to binary converter pls.

Inputs gray code g2, g1, g0 with g2 as most significant and outputs binary code b2, b1, b0 with b2 as most significant.

Two-level circuit.

Thanks.

 

Hopefully this conversion chart will help ya out.
