Abstract :
Digital filter is a important technology of signal processing. This paper introduces the basic theory of digital filter and gives a new method of realization of FIR filter based on TMS320LF2407A fixed-point DSP. This method according to the characteristics of ADC inside the processor, make use of its abundant instruction and vivid programmer to realize. This paper introduce the general frame and the concrete step of realization. By means of calculating of the practicality, it proves that this method aims the design purpose with satisfaction. Practices prove that this method is more fit for the engineering applications for its simple calculation process and high simulation precision.
