中文摘要: |
由于集成许多模块且体积小移动性强,实验箱是目前高校常用的教学设备。学生对数字信号处理技术的实践可在DSP实验箱上进行。为了丰富教学内容和学生的实践内容,在DSP实验箱上进行语音信号的实时滤波,使学生能够直观了解语音处理过程以及滤波效果,同时使学生对无限冲击响应滤波器的极点偏移问题有更实际的认知。该实验可为语音的其它处理提供实践参考。 |
英文摘要: |
Due to the integration of many modules, the small size and strong mobility, experiment box is the commonly used teaching equipment in colleges and universities. For students, the practice of digital signal processing technology can be carried out on DSP experiment box. In order to enrich the teaching content and students" practical content, real-time filtering of speech signal is carried out in the DSP box, where students can intuitively understand the speech processing and corresponding results. Moreover, students can have a more practical understanding on the problem of the pole offset in infinite impulse response filter. This experiment can be a practical sample for other speech processing. |
