hi!!! i badly need help...
*DESIGN A 4 BIT COMBINATIONAL CIRCUIT SO THAT THE OUTPUT IS 1 IF THE DECIMAL NUMBER REPRESENTED IS BY THE INPUTS IS EXACTLY DIVISIBLE BY 3. ASSUME ONLY VALID BCD DIGITS OCCUR AS ITS INPUTS.

tnx in advance...
 

write the numbers 0 to 9 in binary in 4 bits the inputs greater than 9 wil be "dont cares". give the name A B C D to the digits respectivly (most significant one is A). for 0, 3,6 and 9 the output will be 1. Then use the Kmap to derive the function. I think it will be f=C(D'B+B'D)
