| Abstract: | The principle of spectrogram analysis, hardware structure and software design of the digital voice signal spectrometer based on TMS320C50 is introduced in this paper. TMS320C50 digital signal processor used as a coprocessor makes FFT operation, host processor PC analyzes data and displays the result, the communication between C50 and PC is realized by RS232C serial interface. The virtual panel and display window of the digital voice signal spectrometer is built up by using the flexible data processing function and powerful programmability of PC. |
