| Abstract: | Tgrough the development of TMS320C25E development/fast speed process- ing panel,we realized the fast speed sampling of phonetic signal.We could chose the sampling frequency in a prescribed range.At the same time,we can demonstrate the dy- namic graph of phonetic,signal stored in main memory or disk at high speed.In the present article,we introduced the principle and software realization of the sampling of phonetic signal and the fast demonstration of dynamic graph. |
