本论文主要研究了滚动轴承故障诊断的几种方法,其中有传统的也是经典的信号分析方法? ?时域分析法和频域分析法;主要介绍了现代的信号分析法? ?时间序列分析法。 - Firstly , it introduces the development of speech coding , along with the significance of the low bit rate speech coding . it also compares the model of traditional dualistic excitation lpc vocoder and the multi - band excitation vocoder , and lucubrates the analytical method of frequency domain and time domain in the parameter extraction of multi - band excitation vocoding . secondly , based on the parameter extraction operation of keynote cycle , it adopts time domain in rough estimate operation of keynote and frequency domain in fine estimate operation of keynote , in according to the immediacy required in practice , to minish operation amount
本文阐述了一种基于fpga的多带激励语音编码器的研究与设计,首先介绍语音编码研究的发展状况以及低速率语音编码研究的意义,接着对比分析了传统二元激励lpc声码器模型和多带激励编码器模型,并深入研究了多带激励语音编码参数提取的频域和时域分析法,然后根据实际应用的实时性要求,为了减小运算量,在基音周期参数的提取的算法实现上,本文采用在时域进行基音粗估运算,在频域进行基音精细估计运算。
