WebThe experiments illustrate how it is possible to control the motor shaft at a desired angular position by applying high frequency dither signals that satisfy the assumption of the averaging theorem, while other dither signals that do not fulfill the conditions do not give a stable closed-loop system, despite their high frequency content. Web抖動（英語： dither ），是在數位訊號處理領域的中一項用於降低量化誤差的技術。 透過在較低位元中加入雜訊，藉此破壞諧波的排序，使諧波的影響受到壓制，並減少量化誤差 …
Web25 sep. 2013 · Abstract: We propose a 90° phase-shift digital delay-locked loop (DLL) with a new dithering jitter suppression scheme. Delay-line control code dithering is effectively suppressed by comparing the distribution of the input and the output clock jitter. The proposed scheme is analyzed through a stochastic calculation.
