摘要
探讨了3种FM数字解调的算法,给出相应的公式推导,并由此得出了算法和系统模块。在此基础上,通过对TI公司的TMS320C54x系列DSP实际应用,分析了各种方法的优缺点及各自的应用场合,并对一段信号,采用3种方式解调的结果进行了比较。
In this paper,three different manners of FM signal digital demodulations are researched,the paper also gives out their formula derivations and obtains their algorithm and system modules.Based on this,with the applying of TI＇s TMS320C54x series DSP processor,strongpoint and weakness of the three manners are analyzed,also their applied occasions.And demodulating results of a same signal with three manners are also discussed.
