1.2. Obtaining a computer-generated plot of a continuous-time signal requires some care in choosing the time increment (the spacing between points).As mentioned in Section 1.1, too large of an increment will cause a jagged plot. Moreover, a very large time increment may introduce a phenomenon known as aliasing, which distorts the information given in the signal.(Aliasing is covered in greater detail in Chapter 5.) To avoid aliasing when defining a computer-generated sinusoid such as choose A rule of thumb in the case of a decaying sinusoid such as is to choose (Choosing even smaller values of creates smoother plots.) (a) Compute the maximum time increment for plotting in MATLAB. Verify your result by plotting x(t) for to with the following time increments: Note the apparent change in frequency in the plot due to the aliasing effect for How do you expect your plot to appear when Verify your result. (b) Compute the maximum time increment for plotting Verify your result by plotting x(t) for to with 0.5,1.5,and 2 sec.

Consider the following generator matrix: g= (1 0 0 0 1 0 0 0 1 1 1 1 1 0 1 1 1 0) find all the codewords generated by this generator matrix. determine the number of errors that this code will detect. determine the number of errors that this code will correct. prove that a linear code's minimum weight is equivalent to its minimum distance. that is, where c is a linear code, dist(c) = wh(c)

Write a pseudocode solution for each of these problems. 1. design a while loop that lets that user enter a number. the number should be multiplied by 10, and the result stored in a variable named product. the loop should iterate as long as product contains a value less than 100. 2. design a do-while loop that asks the user to enter two numbers. the numbers should be added and the sum displayed. the loop should ask the user whether he or she wishes to perform the operation again. if so, the loop should repeat; otherwise it should terminate. 3. design a for loop that displays the following set of numbers: 0, 10, 20, 30, 40, 50 100. 4. design a nested loop that displays 10 rows of # characters. there should be 15 # characters in each row. 5. convert this for loop to a while loop. declare integer count for count = 1 to 50 display count end for 6. find the error in the following pseudocode. declare boolean finished = false declare integer value, cube while not finished display “enter a value to be cubed.” input value; set cube = value ^ 3 display value, “ cubed is “, cube end while

1)consider the following code snippet: #ifndef book_h#define book_hconst double max_cost = 1000.0; class book{public: book(); book(double new_cost); void set_cost(double new_cost); double get_cost() const; private: double cost; }; double calculate_terms(book bk); #endifwhich of the following is correct? a)the header file is correct as given. b)the definition of max_cost should be removed since header files should not contain constants. c)the definition of book should be removed since header files should not contain class definitions. d)the body of the calculate_terms function should be added to the header file.
