Design of a kind of teaching-practical signal generator

Yi Luo

Abstract

A kind of teaching-practical signal generator is researed in this design,using direct digital frequency synthesis technology,combined with MCU used to control and display,and using a FPGA to realize DDS.This system's waveform can be achieved conveniently,signal output stable and smooth,cost low,and can Meet the teaching requirement.Therefore,it has the practical significance.
