这是一个对实数序列进行FFT变换求频谱的C语言程序,是提取语音MFCC参数的必经步骤,比一般的基于2或4的FFT能节约一半的存储空间和一半的运算量,经DSP的CCS调试成功,是本人改进的、用于本人导师故障诊断项目的一个源程序代码。-This is a real number sequences transform FFT spectrum for C language program is extracted voice MFCC parameters necessary steps than a typical 2 or 4 based on the FFT can save half the storage space and half of the computation by the DSP

DSB
DSB-SC信号的生成与解调
1) 用离散(DSP)的方法生成DSB信号
2) 载波频率为150KHz,音频为500Hz和2000Hz的混合音。
3) 加入高斯白噪声
(4) 语音信号
的传输。
改变抽样频率和量化台阶大小,观察重建信号以及量化噪声信号的波形;对于语音信号主观评价声音质量的变化。
-DSB-SC signal generation and demodulation 1) Discrete (DSP) methods to generate DSB signal 2) the carrier frequency to 150KHz, audio 500Hz and 2000Hz for the mixed tone. 3) by adding white Gaussian noise (4) transmission of voice signals. Change the sampling frequency and quantization step size, to observe the reconstruction of signal and quantization noise signal waveform for subjective evaluation of the speech signal changes in sound quality.

This makes it ideal for Internet/network applications―especially with large images and low bandwidths―as the image can be seen instantly on the decoding side, even with low-speed networks or image databases. The lower subbands are shown first, and more detail is added as time progresses.
