A receiver section recovers the in-phase and quadrature components of a linear modulated data signal. An embodiment of a method includes driving a digital input line with a signal, the signal alternating between a first state and a second state. The second solid may be polymerized to form a polycarbonate. Alternatively, one of the male screw rotor and the female screw rotor has the unequal lead screw formed into a perpendicular-to-axis cross-sectional shape that is constant.
