For an n - variable Boolean function maximum number of prime implicants is

In a half-subtractor circuit with X and Y as inputs, the Borrow (M) and Difference (N = X - Y) are given by

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