Design and implementation of AWG equation editing software

Math equation editing is one of waveform editing methods in arbitrary waveform generator（AWG）,which has many advantages,such as the convenience of math expression,the preciseness of generating signal and so on.Basing on compiler theory,this paper gives the design and the implementation steps of AWG equation editing software,particularly introduces the design methods of lexical analysis,syntactic analysis,calculation and result-stored table of equation expression,which are used to implement the function of simultaneously editing and calculating multi-variable and multi-equation.Results show that this design is reliable,flexible and effective,and it has good application value.
