Error analysis of synchronous frequency measurement method and accomplishment of the method in MCU mea surement systems

Weng Weiwei,Ding Tianhuai(Tsinghua University,Beijing100084,China)  
The elaborate error analysis of synchronous frequency measurement method is presented and some amelioration of the method based on the analysis is proposed.From this,the article proposes how to apply the method and choose its parameters in practi-cal systems.A practical method to accomplish the measurement in MCU systems is also proposed.An example of high precision frequency measurement in a pressure gauge il-lustrates the proposed concepts.
