The method consists of real-time estimation of signal frequency, synchronous tracking of sampling frequency and error correction of harmonic coefficients.

该方法包括信号频率实时估计、采样频率同步跟踪和谐波系数误差校正几个要素。

ASM also provides an error correction formula deduced from matrix inversion theorem to clear up the error originated from approximate synchronous sampling.

近似同步法还提供了一个用基于系统辨识的矩阵反演定理导出的误差校正公式，它能消除近似同步采样造成的原始误差。

Furthermore the audio signal after re-multiplexer with the new PCR correction method can meet FM synchronous broadcast requirements for a more accurate time.

采用该修正 算法修正的再复用器的音频信号可满足对时间要求更苛刻的调频 同步音频 广播的要求。
