Two voltage waves of equal amplitude, V0, and frequency w, propagate in the forward z direction in a lossless transmission line of characteristic impedence Z0. One waves is phase-shifted from the other by \o radians.
a) Find an expression for the net voltage wave formed by the superposition of the given voltages. To do this, express both the given waves in phasor form. Combine the two algebraically, and convert the result back to real instantaneous form, to produce a single wave function.
b) Find an expression for the net current in the line.
