Input your answer in bits, and remember to consider only S3S2S1S0, i.e. discard Cout.Answer:What answer do you expect in decimal? If you are not getting the 2c equivalent of that answer,consider the following as you troubleshoot your circuit:• Did you remember to discard the final carry out?Check the bits you used as input. If you followed the circuit diagram as shown previously,the bits are arranged A3 B3 A2 B2 A1 B1 Ao Bo Cin. The first input (-5) corresponds toA3A2A¡Ao with Ag as the MSB.• You must input the operands as is, i.e. let the circuit do the negation for you.08 OOv O18 OO A1za OS1O A2

2. Design a combinational circuit with three inputs, x, y, and z, and three outputs, A, B, and C. When the binary input represents any of the decimal digits 1, 2, 3, or 6, the binary output should represent the decimal digit that is one greater than the input, that is 2, 3, 4 and 7, respectively. Similarly, when the binary input represents any of the digits 4, or 7, the binary output should represent the digit that is two less than the input. The remaining two inputs, that are the binary representations of the decimal digits 0 and 5 never occur.

2. Design a logic circuit with two inputs and 4 outputs, with each of the outputs hooked up to an LED. Only the first LED should light up when the input values are 00. Only the next LED should light up with the input values are 01. Only the following LED should light up for 10, and only the last LED should light up for input 11. Thus for each input combination, you should have one LED only being lit. This is called a DECODER circuit, you are decoding 2 bit binary input to one of 4 discrete outputs. a. Create the truth table (use the standard truth table format). b. Write a Boolean expression that corresponds to the truth table.

6. Design a circuit that will tell whether a given month has 31 days in it. The month is specified by a 4-bit input. For example, if the inputs are 0001, the month is January, and if the inputs are 1100, the month is December. The circuit output, Y, should be HIGH only when the month specified by the inputs has 31 days in it. Write the simplified equation, and draw the circuit diagram using a minimum number of gates. (Hint: Remember to take advantage of don't cares.)
Design a combinational circuit that increments the 4-bit binary input. The output of the circuit is also represented as 4 bits. For example, if the input is 0011 then the output is 0100. Note: the increment of 1111 is 0000. Let the input variables be A, B, C, and D, while the output variables be W, X, Y, and Z. What is the boolean function (in sum of minterm format) of output W?
