Question 1: A pressure gauge which can be modeled as a Linear Time-Invariant (LTI) system has a time response to a unit impulse input h(t) given by (Ge-2t +e-«") u(t). For a certain unknown input, the output y(t) is observed to be (4e7t – 8e2")u(t). For this observed measurement, derive the true pressure input x(t) to the gauge as a function of time. Assume that the input signal is right-sided.

Problem 7.65 - Enhanced - with Hints and Feedback Figure 3 m C 6 m Part A 4 of 15 > ■Review 12 kN/m 1 of 1 Draw the shear diagram for the beam. Follow the sign convention. (Figure 1) Click on "add vertical line off" to add discontinuity lines. Then click on "add segment" button to add functions between the lines. Note 1 - You should not draw an "extra" discontinuity line at the point where the curve passes the x-axis. Note 2 - The curve you choose from the drop-down is only a pictorial representation of a real quadratic/cubic curve. The equation of this curve is not mathematically equivalent to the correct answer. Consequently, slopes at discontinuities and intercepts with the x-axis (if any) are not accurate. Note 3 - Be sure to indicate the correct types of the functions between the lines, e.g. if in your answer the type of a function is "linear increasing slope" for the function that actually has linear decreasing slope, the answer will be graded as incorrect. Use the button "change…
