Designing function generator and carrying the frequency synthesis are the unique applications of memory.Starting from the basic principle of memory,we carry out the theoretical studies according to the sampling theory,summarize out the functions of function transformation of the memory,put forward the idea of using the DDS method to design the function generator.Based on this an application of using EPROM to construct the programable contnuous function generator containing many kinds of simulation signal was given The result indicates that the function generator designed in this method has the properties of higher intelligent degree and easier controlling on the parameter.
