Abstract
As a core component for open-loop characteristics testing system of micro-sensor, quality of signal source influences the integer performances of testing system directly. The method to generate special signal of open-loop testing system of resonant micro-sensor are discussed in this paper, and a method of direct digital frequency synthesize (DDS) to develop the special signal source of the testing system is proposed. A designation approach based on DSP and FPGA in the realization of DDS is advocated. Finally a simulation is made using the MATLAB. The principle of DDS is also introduced.
