Digital discriminator circuit design based on DSP

摘要

For software radio applications and multi-band received signal processing characteristics, based on the analysis for analog discriminator circuit, Implementation method that analog circuit is substituted by the digital processor is discussed. The mathematical model of the system to convert analog to digital transmission function is researched. Through the functional simulation under the software program development environment of CCS, its effectiveness is verified. And the implementation method which changes analog to digital system is able to be used wildly.
