Design and Implement of FIR Filter Based on CCS and FDAtool

In order to solve the problem that the digital signal system processing is complicated in setting the system parameters, the paper proposes a method for setting the system filter coefficients based on the combination of CCS and FDAtool. The method mainly uses FDAtool is to have the characteristics of graphic visualization, simple and fast analysis of the system frequency spectrum. By analyzing the FIR filter structure, the system filter coefficients are designed. At the same time, the DSPF28335 chip with fast real-time signal processing, which was used to analyze the system signal processing in CCS environment. The design results show that the combination of FDAtool and CCS can seamlessly perform signal processing, meanwhile, the interface has GUI functions and can to achieve the purpose of real-time analysis system.
