Please answer the following questions by entering Python expressions in the boxes provided. Your answers may contain any of the following:

  • omega represents \omega
  • OMEGA represents \Omega
  • sin and cos represent \sin(\cdot) and \cos(\cdot), respectively
  • sqrt represents the square root function
  • e, 1j, and pi represent e, j, and \pi, respectively
  • Re and Im represent {\rm Re}(\cdot) and {\rm Im}(\cdot), respectively

Consider the CT signal x(\cdot) defined by the following plot (you can assume that x(t) = 0 for all t not shown in the plot below):

This function has a Fourier transform given by X(\cdot). A portion of the magnitude of the Fourier transform is shown below:

Determine a simple expression for b in terms of the parameters of x(\cdot).
When entering your answer, you may use t_1 to refer to t_1, t_2 to refer to t_2, and/or a to refer to a.
b =~
