Abstract:
(EN) The embodiments of the present application provide a method, a device and a system for detecting the mean value of a signal. The invention designs a reconstructed signal which has a designated common-mode voltage and has the same output swing and polarity as that of an input signal, to enable the mean signal of the reconstructed signal and the mean signal of the input signal to include the same deviation component, and then performs subtraction between the mean signal of the input signal and the mean signal of the reconstructed signal, to counteract the deviation component included in both, thereby eliminating the deviation of the mean value of the input signal, and obtaining an ideal mean value of the input signal.
(FR) Les modes de réalisation de la présente invention concernent un procédé, un dispositif, et un système de détection de la valeur moyenne d'un signal. L'invention conçoit un signal reconstruit ayant une tension de mode commun désignée et les mêmes excursion et polarité de sortie que celles d'un signal d'entrée, ce qui permet au signal moyen du signal reconstruit et au signal moyen du signal d'entrée d’inclure la même composante de déviation. L’invention exécute ensuite une soustraction entre le signal moyen du signal d'entrée et le signal moyen du signal reconstruit pour contrebalancer la composante de déviation incluse dans les deux, ce qui permet d'éliminer la déviation de la valeur moyenne du signal d'entrée et d'obtenir une valeur moyenne idéale du signal d'entrée.
(ZH) 本申请实施例提供了一种信号均值检测方法、装置和系统。通过设计具有指定共模电压且与输入信号的输出摆幅和极性相同的重构信号,使该重构信号的均值信号与输入信号的均值信号包含相同的偏差成分,然后将输入信号的均值信号与重构信号的均值相减,将两者包含的偏差成分抵消,从而消除输入信号的均值的偏差,得到输入信号的理想均值。
