The outputs of the two flip-flops Q₁, Q₂ in the figure shown are initialized to 0, 0. The sequence generated at Q₁ upon application of clock signal is

To maximize power transfer, a lossless transmission line is to be matched to a resistive load impedance via a $$\lambda /4$$ transformer as shown.

Which one of the following field patterns represents a TEM wave traveling in the positive $$x$$ direction?

In the transmission line shown, the impedance $${Z_{in}}$$ (in ohms) between node A and the ground is
