SSB has an advantage over AM with respect to efficiency and power gain. Why, then, is AM commercial broadcast being replaced with SSB transmission?
Show that the language F = {a^i b^j c^k | i, j, k greater than or equal to 0 and if i = 1 then j = k} is not regular. Show, however, that it satisfies the statement of the pumping lemma
Design and draw the state diagram (graph-representation) of a deterministic finite-state automata that recognizes the language generated by the grammar
Create and implement a lexical analyzer for C-- as follows: Write the set of token types to be returned by lexical analyzer. Explain regular expressions for this set of token types.
Non-terminal A is useless if there is no derivation from start symbol to string of tokens in which A appears. Write a mathematical formulation of this property.
Give a construction that assumes you are given a DFA for L and show how to construct an NFA (with or without ε-moves) to recognize sort(L).
Goal is to find expedition of maximum profit. Either show that there exists polynomial-time algorithm for GDP, or show that corresponding decision problem is NP-complete.
Describe why every nonempty propositional clause, by itself, is satisfiable. Prove rigorously that every set of five 3-SAT clause is satisfiable, given that each clause mentions exactly three distinct variables.
Write down the set of token types to be returned by your lexical analyzer. Describe regular expressions for this set of token types.
Consider a logic function with three outputs, A , B , and C , and three inputs, D , E , and F . The function is defined as follows: A is true if at least one input is true, B is true
Rewrite the productions for each of the following nonterminals as right regular grammars: Identifier, Float. Show the moves made using the DFSA for identifiers in accepting.
How many equivalence classes does this relation have and what are they? Use these equivalence classes to construct the minimal DFA for the language.
Design Turing machine (using Sipser notation) having at least 4 nontrivial (i.e., nonrejecting) states and at least six nontrivial (i.e., not to the rejecting state) transitions.
