By using multi-point sampling with one oxygen meter, the operator of the chamber can find out the leakage points according to the density of oxygen detected and take necessary measures to prevent accident in time.

Robust stability of multirate input control system;

Design of multistage and multirate filter;

This paper studies the impact of the multi-rate signal processing technique and rate conversion of sampling data on the differential current of the differential protection and proposes an effective sampling rate conversion mechanism with cascade connection of decimation and interpolation,by which .

In the infrared push-broom systems of satellites,the multiple sampling technology is widely used to improve the performance of systems.
