| Abstract: | Currently the common laboratory signal source generally is generated by analog circuit. There are some weakness ahout analog signal such as indirect display, output unsteady and low resolution, etc.This paper introduces a basic method and principle using the technology of DDS PLL to realize digital signal source. Digital circuit have some advantage such as direct importation, operation simple and direct display to satisfy the effective demand of laboratory. |
