DISTORTION REDUCTION METHOD AND APPARATUS FOR LINEARIZATION OF DIGITAL PULSE WIDTH MODULATION BY EFFICIENT CALCULATION |
摘要 |
A system and method for reducing distortion (52) in a pulse width modulated digital system by selectively implementing linearization (46). The linearization is implemented computationally efficient, using no division operations. A frequency detector (42) is implemented which causes signals (44) to bypass the linearization algorithm at frequencies where the new modes of distortion become significant as a result of the linearization when used in combination with an interpolation filter (40).
