Design And Realization Of Digital Filter And Its Application System Based On DSP

DSP technology means the technology to accomplish digital signal processing.Nowadays DSPs are getting more and more attentions in the information field due to toits powerful signal processing ability, becoming a hot-point technique in communication and other relating signal processing areas.DSP chip is especially eligible for digital signal processing. Its main application is alizing all kinds of digital signal processing arithmetic.The paper deeply discusses the filter's software realization based on TMS320C5402, realization of FIR filter with window function, realization of FFT/IFFT arithmetic with time-drawing.The author realizes three-segment equalizer,and accomplishes the design on digital signal processing experimental system.
