2. The function F(x,y,z,w) is used in a combinational circuit that can generate a binary output of 1 when the number of variables having binary input of 0 is greater than the number of input variables having binary input 1. The combinational circuit generates a binary output of 0 when the number of variables having binary input of 0 is less than the number of input variables having binary input 1, the circuit generates a don't care when the number inputs having l's equals the number of inputs having zeros. i- Complete the truth table of F as a function of the inputs (x.y,z,w)
