digital signal processing book

I have always been interested in speech signal processing technology, but I have also been confused about its future development and application, the main branch of speech signal processing technology is summarized and summarized to discuss with everyone the development direction and new applications of speech

periodic and the Pi and 3pi,5pi,7pi are the same phase. The domain value of the man-defined phase spectrum is (-PI,PI], so the phase difference in the graph is pi.Finally come a large collection:Four, Fourier transform (Fourier transformation)I believe that through the previous three chapters, we have a new understanding of frequency domain and Fourier series. But the article at the beginning of the piano spectrum example I said that this chestnut is a formula wrong, but the concept of a typica

Speech Signal Processing-Vector Quantization) Zouxy09@qq.com Http://blog.csdn.net/zouxy09 This semester I have a speech signal processing course, and I am about to take the test. So I need to know more about the relevant knowledge. Haha, I have no lectures at ordinary times, but now I have to stick to it. By the way,

reproduced in the original: http://blog.csdn.net/ziyuzhao123/article/details/12004603 thank you very much. First, the pre-emphasis of voice signal The pre-emphasis of speech signal is to aggravate the high frequency part of speech, to remove the influence of lip radiation, and to increase the high frequency resolution of speech. In general, the transfer function is a first order FIR high-pass

The book "Advanced Programming in UNIX environments" comes with many small and exquisite programs. When I read this book, rewrite the code in the book according to your own understanding (most of them are on the copybook) to deepen your understanding (it's too difficult to read a book, huh, huh ). This example is succe

Digital image processing vocabulary Algebraic operation algebra is an image processing operation that includes the sum, difference, product, and quotient of the two images corresponding to pixels. Aliasing is a kind of artificial trace generated when the pixel distance between the image and the image details are too large. A part of an arc chart, indicating a co

If it's black, write a purple one. Anyway, a little practice.Since 8 can say, then from red to black into 16384 part, that is , said, the line is not OK, of course.
