Inverse Fourier Tranform of Transmission Lines Wave Equation

Click For Summary
The discussion revolves around the difficulties in calculating the inverse Fourier transform of e^(-jwx/u) in the context of transmission line wave equations. The user expresses confusion regarding the application of Fourier and Laplace transforms to solve the partial differential equation (PDE). Feedback emphasizes the need for clearer notation and consistent variable definitions to facilitate understanding. The importance of careful problem formulation and proper typing instead of using images is highlighted. Overall, clarity in notation and a structured approach to the problem are essential for successful resolution.

From the derivation of v(x,t) and i(x,t) I am stuck on how the inverse Fourier transform of e^(-jwx/u) was calculated. I am trying to understand how the PDE was fully solved here: http://fourier.eng.hmc.edu/e84/lectures/transmission_line/node1.html

Homework Equations


Not sure what rule to implement here, working using laplace transforms (s = jw) to perform Fourier transformations to avoid integration.

Your notation and writing are a mess. You have f as a function of x in some places, of t in other places, and x and t in yet other places. Why don't you start by clearly defining what the problem is and writing it out carefully.
 
And type it instead of posting an image.
 
Question: A clock's minute hand has length 4 and its hour hand has length 3. What is the distance between the tips at the moment when it is increasing most rapidly?(Putnam Exam Question) Answer: Making assumption that both the hands moves at constant angular velocities, the answer is ## \sqrt{7} .## But don't you think this assumption is somewhat doubtful and wrong?
