Question 1:

There are three inputs to a system. The first two inputs are compared and if they are same the output will be 1

otherwise it will be 0. The output of first two inputs is then compared to the third one. If both are same output will

be 1,otherwise it will be 0. Construct a truth table and a combinational circuit for the above problem.


Question 2:

A circuit detects alternating inputs and gives 1 at output. For example if the input is 101 or 010, output will be

high but it will be 0 for 001 or 111 etc. You have to design such a circuit for three inputs.
Question 3:

There is a three input combinatonal circuit. Its output is 1 when the binary value of the input is odd. For example it

will be 1 for 001 or 101 etc. Design the above mentioned combinational circuit.
Question 4:

In a talent show there is a panel of three judges that decides if the contestant goes to the next level or not. For a

contestant to go the next level at least two judges vote 1, which will make the output 1. Design a combinational

circuit to fulfil the task.
