摘要

提出了正弦输出直接数字频率合成器正弦振幅近似的一种新方法——抛物线近似。所提出的近似提供了一个初始猜测，它比以前的近似更接近目标正弦振幅，并且可以简单地使用全数字电路实现。

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.
