Figure Q5 shows the cross-section of the typical layout of two tracks (A and B) on a
printed circuit board with a ground plane C. The tracks are terminated as shown in the
figure, with track A carrying digital signals. You can assume that the lines are
electrically short.
Q5
Draw the equivalent circuit that models the crosstalk and write down a
relation between the voltage applied to track A and the voltage coupled on to
track B at low frequencies, VNE-

Discuss the potential of wireless power transfer technologies, such as resonant inductive coupling, for charging electric vehicles and IoT devices.
During the first month of work, you get an assignment to perform a measurement campaign to estimate the channel path loss exponent for a new wireless product. You performed field measurements and collected the following data: Reference path loss: PL(d0) Path loss measurements: PL (d1), PL (d2), ... PL (dn), at distances d1 … dn Using the path loss exponent model, find an expression for the optimum value of the path loss exponent n, which minimizes the mean square error between measurements and the model. Hint: the optimum value of n should minimize the mean square error (MSE) between your predicted path loss and measured path loss.
