Question 18 1 pts Which is more appropriate for applications that involve computation of the upper bounds of the data rate that a communications channel can accommodate? O Information Theory O Coding TheoryQuestion 17 1 p Which is more appropriate for applications that involve manipulating the bits of information for better data compression? O Information Theory O Coding TheoryQuestion 19 1 How can trigonometric functions be used in digital communications technologies? O The formula are used to predict future values of bits in a codeword. O Trigonometry is not applicable to digital communications technologies. O Information is encoded in the amplitude, frequency or phase of the wave function. O Trigonometry is not math.Question 16 1 pts This principle relates the information capacity of a digital communications channel to the bandwidth and signal- to-noise ratio. O Shannon's Associative Law O Shannon's Identity Law O The Shannon-Hartley Capacity Theorem O Hartley's LawQuestion 20 What is a correct perspective on modular arithmetic? O The set of all integers is partitioned, and equivalence classes are operated on, instead of the original integers. O All computations are like the usual algebra, only that mod is attached in the end of an equation. O Modular arithmetic is a branch of mathematical analysis. O The mod function is like sin, log or tan.Question 11 Why is it important to tabulate values of the cost function in a linear programming problem? O to determine points of intersection O to minimize cost O to obtain the final shaded region O to minimize profitD Question 14 1 This condition is in effect when the correct ordered pair is selected, for the cost function, after the tabulation step in a linear programming problem. O minimum cost O constraints (in general) O maximum profit O default constraintsQuestion 12 1 pts These are in effect because of the conditions on the variables that can be found in the statement of a linear programming problem. O minimum cost O maximum profit O constraints (in general) O default constraintsQuestion 13 1 This condition is in effect when the correct ordered pair is selected, for the profit function, after the tabulation step in a linear programming problem. O minimum cost O maximum profit O constraints (in general) O default constraintsQuestion 15 1 pts This principle relates the information capacity of a digital communications channel to the bandwidth and transmission time. O Shannon's Law O The Shannon-Hartley Capacity Theorem O Shannon's Reciprocity Theorem O Hartley's Law
