What is the sign of operation for the X-OR gate?Q2.What will be the output of an X-OR gate when both inputs are HIGH?Q3.A two-input X-OR gate will produce a HIGH output when the inputs are at what logic levels?Q4.What type of gate is represented by the output Boolean expressionRT ?Q5.What will be the output of an X-NOR gate when both inputs are LOW? ADDERSAdders are combinations of logic gates that combine binary values to obtain a sum. They areclassified according to their ability to accept and combine the digits. In this section we will discussquarter adders, half adders, and full adders.QUARTER ADDERA quarter adder is a circuit that can add two binary digits but will not produce a carry. This circuitwill produce the following results:0 plus 0 = 00 plus 1 = 11 plus 0 = 11 plus 1 = 0 (no carry)
