We use huffman’s algorithm to obtain an encoding of alphabet {a, b, c} with frequencies fa, fb, fc. in each of the following cases, either give an example of frequencies (fa, fb, fc) that would yield the specified code, or explain why the code cannot possibly be obtained (no matter what the frequencies are). (a) code: {0,10,11}. (b) code: {0,1,00}. (c) code: {10,01,00}.

Design a pos circuit that displays the letters a through j on a seven-segment indicator. the circuit has four inputs w, x, y, and z which represent the last 4 bits of the uppercase ascii code for the letter to be displayed. thus, if wxyz = 0001 then "a" will be displayed. (any answer with 22 or fewer gates and inverters, not counting any for the inputs, is acceptable)
