In 2’s complement addition, an overflow occurs if the result would not fit the number of bits used for the results. For example, suppose we add 127d (0111 1111b) and 127d using 8-bit registers. 127+127 is 254, but using 8-bit arithmetic the result would be 1111 1110b binary, which is the two's complement encoding of -2, a negative number. A negative sum of positive operands (or vice versa) is an overflow. We want to add an overflow flag output (V) to the adder module below to indicate such occurrence. module adder(A,B, sum, V); input [7:0] A, B; output [7:0] sum; output V; assign sum = A +B; assign V= ......(;)/(()/())missing code endmodule What is a correct statement for V? Group of answer choices assign V = A[7]&B[7] | (~A[7])&(~B[7]); assign V = A[7] ^() B[7]; assign V= A[7]&B[7]&sum[7] | (~A[7])&(~B[7])&(~sum[7]); assign V = sum[7]; assign V= A[7]&B[7]&(~sum[7]) | (~A[7])&(~B[7])&sum[7];

Cascade control Problem 1. For the paper drying process shown in the figure below, the following information is available: The flow control loop (FIC47) can be represented by a first-order lag with a gain of 4 (m³ h⁻¹)/%CO and a time constant of 0.1 min. The transfer function of the air heater outlet temperature to the fuel flow is a second-order lag with time constants of 2 min and 0.8 min. A change in fuel flow of 1 m³ h⁻¹ causes a change of 2°C in the outlet air temperature. The drier can be represented by a first-order lag with a time constant of 5 min. A change of 1°C in inlet air temperature causes a change in outlet moisture of 0.5 mass percent. The moisture transmitter (MT47) has a range of 0 to 6 mass percent and a negligible time constant. Air Wet paper Paper product Drier MT Hot air Hot 47 gases mois Ambient air Heater MC SP 47 Frset SP FIC 47 FT 47 F Combustion Fuel air (a) For the control scheme shown in the figure, draw the block diagram of the moisture control loop showing the transfer functions. Decide on the fail position of the control valve and the controller action, and make sure that the signs in your block diagram correspond to your decisions. (b) Consider a cascade control scheme using an outlet temperature sensor with a range of 120 to 170°C installed on the air line from the heater to the drier and a temperature controller to manipulate the fuel flow set point; the output of the moisture controller (MC47) sets the set point of the outlet air temperature controller. Draw the instrumentation diagram and the block diagram of the cascade control scheme. Show the defined transfer functions on the block diagram, and specify the action of each controller.

Copy and Paste the Table into your Word document. Use the results to answer the following questions in your Word document: 1. Should the assembly line be shut down so that the machine can be re-calibrated? Use a 0.01 level of significance. 2. Explain why a level of significance of \( \alpha = 0.01 \) is more reasonable than \( \alpha = 0.1 \). [ Hint: Consider the consequences of incorrectly rejecting the null hypothesis.]

8 Check my work Exercise 6-15 (Algo) Operating Leverage [LO6-1, LO6-8] Magic Realm, Incorporated, has developed a new fantasy board game. The company sold 37,200 games last year at a selling price of $61 per game. Fixed expenses associated with the game total $651,000 per year, and variable expenses are $41 per game. Production of the game is entrusted to a printing contractor. Variable expenses consist mostly of payments to this contractor. Required: 1-a. Prepare a contribution format income statement for the game last year. 1-b. Compute the degree of operating leverage. 2. Management is confident that the company can sell 46,128 games next year (an increase of 8,928 games, or 24%, over last year). Given this assumption: a. What is the expected percentage increase in net operating income for next year? b. What is the expected amount of net operating income for next year? (Do not prepare an income statement; use the degree of operating leverage to compute your answer.) Complete this question by entering your answers in the tabs below. Req 1A Req 1B Req 2 Prepare a contribution format income statement for the game last year. Magic Realm, Incorporated, Contribution Income Statement Sales Variable expenses Total Per Unit
