The present publication describes a data transfer method and system in a digital sound reproduction system. The method comprises method steps for generating a digital audio stream for multiple channels in a host data source, e.g. a computer, the audio stream is formed by multiple consecutive samples, receiving the digital audio stream sent by the host data source through a digital data transmission network by several digital receivers each of which including a microcontroller with a clock, the receivers further including means for generating an audio signal. In accordance with the invention the host data source sends repeatedly a synchronization sample to at least one receiver, the receiver replies to the synchronization sample by a return sample, the host calculates a latency (T) for each receiver based on the sending time (Th1) of the synchronization sample and the reception time (Th2) of the return sample and the processing time (Tt1-Tt2) of the receiver, the host sends to the receiver information of the calculated latency (T) in combination with the time stamp the measurement time, based on this information the receiver adjusts the function of its clock, and the above synchronization steps are repeated continuously.

A method for reducing an effect of a disturbance signal on an output of a dynamic system. The method includes generating an increment of the disturbance signal, and modifying an incremental signal input to the dynamic system based on the increment of the disturbance signal, thereby reducing the effect of the disturbance signal. According to one embodiment the method includes generating an increment by calculating a difference between two values sampled during consecutive sampling periods, wherein a first one of the two values is sampled during a first one of the consecutive sampling periods, and wherein a second one of the two values is sampled during a second one of the consecutive sampling periods, and wherein the two values are disturbances.

The invention relates to a pulse baseline value calculation method and a particle counting method for a blood cell analyzer. The pulse baseline value calculation method comprises the step of calculating the average value of n consecutive sampling data on the condition that the absolute value of the difference between two arbitrary adjacent data among the n consecutive sampling data is smaller than a baseline threshold value and the n consecutive sampling data are nearest to a pulse starting point within a pulse non-sustainable period, wherein the average value represents the baseline threshold value. According to the technical scheme of the invention, the baseline threshold value is preset and compared, and the sampling data of a noise-superimposed baseline are avoided. Meanwhile, sampling data within a noise / interference allowable range are selected and calculated. In this way, the noise is accumulated onto a final baseline value, so that the baseline value is more close to real data. The misjudgment of the baseline value is greatly reduced, so that the particle counting result is more accurate. The method can be applied to the particle counting operations of three-category type blood cell analyzers, five-category type blood cell analyzers, flow cytometers and other biochemical instruments.
