Q5) Design a 4-bit input combinational logic circuit whose output (F) '1' if the input is divisible by 3 without Remainders otherwise, it is equal to '0'. 1) List the truth table 2) Write the Boolean expressions for the output (F). 3) Draw the logic circuit.

13)In a ladder logic program, one should never A)use the name of a coil for a contact B)use a coil with a designation other than %Q C)use the same coil as an output on more than one rung D)use the same contact on more than one rung

1D) For a combinational logic circuit of four inputs and one output having following conditions:  if the number of 1’s in the inputs are odd then output is 0  if the number of 1’s in the inputs are even then output is 1 a. Draw the truth table b. Find the simplified logic function using K-Map
