Half Adder The half adder is a circuit that accepts two binary inputs and provides the binary sum as the output. Two outputs are provided; the sum and the carry. A half adder is used for adding the first two digits of binary numbers that are being added together. In other words, they are only used to add 0+0, 0+1, 1+0 or 1+1. If you add larger binary numbers together you would still use a half adder for the first two digits, but beyond that each stage would use a full adder. For example, if you were to add 10+11 (2+3) you would use a half adder to add the two Least Significant Bits together (0+1). The next two digits (1+1) would be added using a full adder. XOR AND SUM Owly Build the above circuit using only nand gates (draw diagram in space below) and generate the truth table.

Task 3: Design of 4-to-1 line Data Selector / Multiplexers: A multiplexer (MUX) is a combinational circuit that selects binary information from one of many input lines and directs the information to a single output line. The selection of a particular input line is controlled by a set of input variables called selection inputs. Normally, there are 2n input lines and n selection inputs whose bit combinations determine which input is selected. 4-to-1 Do MUX y D, a) Complete the truth table of the 4-to-1 line multiplexer.

Computer Science Design combinational logic for outputting the wait time associated with each state. For example, state 000 has the main street green light on for 15 seconds. The combinational logic for the input 000 would have an output 1111 corresponding to decimal 15. Let the outputs W3, W2, W1 and W0 represent a binary number corresponding to the wait time.
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. Draw the truth table, and give all the minimal forms for the functions that represent the outputs A, B, and C. U

Design a circuit that takes three bits, X2, X1, X0 as input and produces one output, F. F is 1 if and only if 2<=X<=5 when X = (X2, X1, X0) is read as an unsigned integer. For example, if X2=1, X1=0, and X0=0, then the unsigned binary value is 100, which is 4, so the output would be 1. Your Assignment For This Problem Includes the Following Design the necessary circuit using Logisim to implement the situation described above. Use Kmaps for simplification. Be VERY careful to get the correct functions for your output before simplifying and designing the circuit with Logisim. You should minimize the circuit. Your circuit should have three inputs and one LED output. All inputs (X2, X1, X0) and output (F) should be labeled (in Logisim, not by hand). Please use these names to indicate the inputs and output so all projects are consistent. You should also include your name as a label on the circuit. Test your circuit to be sure it is working correctly.
