Digital filtering occupies an extremely important position in the digital signal processing. Digital filtering is a basic algorithm in the application of the voice and image processing, pattern recognition, spectral analysis and etc. It is beneficial to use digital filter and not use analogue filter in many signal processing applications. FIR digital filter is easy to achieve different amplitude and phase frequency characteristic index, and overcomes the voltage drift, temperature drift and noise problems related to the analogue filter. And using the DSP chip to achieve digital filter has good stability, high accuracy and good flexibility characteristics. Therefore, this subject choice DSP to achieve digital filter.
