An analytical solution of the wave equation for universal drift modes is derived. More exact analytical expressions for the dispersion relation and the damping rate are obtained than have been obtained previously. The spatial amplification of an incident wave is derived from the solution of the scattering problem. The dependence of the convective amplification factor on the shear is then determined.
