A discrete memoryless source (DMS) outputs source letters with probabilities 0.30 , 0.18 , 0.15 , 0.15 , 0.12 , 0.06 , 0.04 i. compute the source entropy (units: bits) ii. design a Huffman code to efficiently encode the source iii. compute the average codeword length for the code (units: bits)

7. design a circuit with three inputs (x, y, and z) representing the bits in a binary number, and three outputs (a, b, and c) also representing bits in a binary number. when the input is 1, 2, or 3, the binary output should be one lesser than the input. when the input is 4, 5, or 6, the binary output should be one greater than the input. when the input is 0, the output is 0, and when the input is 7, the output is 7. show your truth table, all computations for simplification, and the final circuit.
