| Abstract: | This article first introduce the development of the DSP and it's main features,especially the structure and features of DSK produced by TI.Then we illuminate the theory of gudie frequency stereo,and the design project which can realize the gudie frequency stereo with TMS320c50 DSP and TLC32040(AIC).Sampling is finished during the interrupt service routine, and the output waveform is displayed on the oscillograph. |
