Parabolic approximation: a new method for phase to amplitude conversion in sine-output direct digital frequency synthesizers
A new approach in sine amplitude approximation for sine-output direct digital frequency synthesizers "parabolic approximation" is presented. The proposed approximation provides an initial guess, which is much closer to the target sine amplitude than previous approximations and can be simply implemented using full-digital circuitry.
