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