Using Hamming code described in class, design an error correction code (ECC) for a 4-bit data word. Reminder: - Required number of check bits is log2N 1, where N is data word length - ECC bits whose indices are powers of two are used as check bits. - If we write the indices of ECC bits in binary, the check bit with a 1 in position i of its index is the XOR of data ECC bits that have a one in position i of their indices.

Show that there is a language a ⚆ {0, 1} â— with the following properties: 1. for all x â a, |x| ≤ 5. 2. no dfa with fewer than 9 states recognizes a. hint: you don’t have to define a explicitly; just show that it has to exist. count the number of languages satisfying (1) and the number of dfas satisfying (2), and argue that there aren’t enough dfas to recognize all those languages. to count the number of languages satisfying (1), think about writing down all the strings of length at most 5, and then to define such a language, you have to make a binary decision for each string about whether to include it in the language or not. how many ways are there to make these choices? to count the number of dfas satisfying (2), consider that a dfa behaves identically even if you rename all the states, so you can assume without loss of generality that any dfa with k states has the state set {q1, q2, . . , qk}. now think about how to count how many ways there are to choose the other four parts of the dfa.
