Design of multi-function generator
Abstract£ºSignal generator is widely used in communication, teaching, measurement and so on. It is an important tool in signal simulation experiment.In this paper, through the analysis of the working principle of the existing multi function signal generator, according to the requirements of the parameters provided by, decided to use DDS technology, MCU AT89S52 of ATMEL company produces as the master machine and DDS chip AD9854 as signal system to produce the key devices, design a high output frequency, high resolution, low power consumption, produce a variety of waveforms of multifunctional signal generator. The design of the relevant software using C language to complete.
