Read the Case Exercise on page 120. Complete the answers to the questions for the Case Exercise. Complete and thorough, 4-5 sentence answers per questions are required for full points. Case Exercise-Sodium and its effects on out health Recent data show that Americans consume, on average, more than three times the recommended level of sodium per day in their food and beverages. High salt intake contributes to high blood pressure and its complications-stroke, heart attack, congestive heart failure, and kidney failure. In fact, thousands of lives could be saved if sodium consumption were lowered in people with high blood pressure. Write a memo to the U.S. Secretary of Health and Human Services about what might be done to address concerns about the effect of high sodium intake on….

The script shown in Figure D10.2 simulates an AM modulated signal. Verify that the script functions properly using the MathScript Interactive Window. You will need to type the script into the Script Editor. Once you have verified that the script runs properly, open a new VI and using a MathScript Node, develop a VI simulation of the AM modulated signal.

Create front panel knob controls for the signal_freq and carrier_freq variables labeled Signal Frequency and Carrier Frequency, respectively. Use separate Waveform Graphs for both the mod and modified real_freq result. When the VI is ready, set signal_freq = 20 and carrier_freq = 100 and run the

VI. What happens to the signals on either side of the carrier signal (the center frequency) as you move the signal_freq….

Open a new VI and go to HelpFind Examples…. Click on the Search tab, type “express” into the string labeled Enter keyword(s), and press the Search button.

(a) Open Express Comparison.vi, which shows how to compare values using the Express VI. Using the Value A and Value B controls, you can modify the signals. If Value A is greater than Value B, the result will be indicated by a 1 on the graph. If Value A is less than Value B, the result will be indicated by a 0.

(b) Open Express Vibration Lab.vi, which simulates a vibratory system of two masses and springs. The parameters of the system, such as the mass and rigidity of the springs, can be changed. Refer to Context Help for a more….

Consider the following linear, time-invariant system:

Where

The vector x = [x1 x2] T is known as the state vector. The parameter k0 is a constant. The input to the system is u. Develop a script using MathScript to perform the following computations:

(a) For 0 ≤ k0 ≤ 5, compute the eigenvalues of A. The eigenvalues can be complex (imaginary) numbers. Generate a plot of the real part of the eigenvalues versus the imaginary part.

(b) With the input u = 2 for t ≥ 0 and k = 0.5, find the solution using numerical integration and plot x versus t for 0 ≤ t ≤ 20. Use the initial conditions x(0) = [1 0] T
