我们通过Sampling与Quantization来实现这个过程 Sampling 是指,recording an analog signal at regular discrete units of time (例如,每33秒记录一次) Quantization 是指,将所有的 analogue value 映射到一个有限的 digital value set 中去 Analog-to-Digital Converter (ADC) 一个能够对 Analog Data 进行 Sampling ...
The lower coding errors for N=9 and N=13 are clearly seen, which relate to the low quantization errors at the coding layer as demonstrated in Fig. 2. Fig. 3. Top to Bottom: Original spectrogram; reconstructions using input window sizes of 1, 3, 9, and 13 (forcing the coding units ...
Experimental results on speech spectrogram coding demonstrate that the binary codes produce a log-spectral distortion that is approximately 2 dB lower than a sub-band vector quantization technique over the entire frequency range of wide-band speech. Opens in a new tab © 2007 ISCA. Perso...
Gray Coding: Gray Coding is another form of representation that is used ubiquitously in all applications. In Gray coding, the adjacent representations (symbols) differ by only one bit. Gray coding, when combined with Forward Error Correction codes capable of corrective single bit errors, it can ...
Thus, in such a system the coding implementation is relatively simple whereas the logic that controls it is complicated. The COPE architecture, introduced in [13], uses deterministic/opportunistic binary inter-flow NC. The NC technique is applied in between the data link and the network layer. ...

From quantization considerations, the Lee hologram is shown to be the best choice for randomly phase coded objects. When phase coding is not feasible, the Lohmann hologram is preferable as it is easier to plot.doi:10.1080/713821662Krishna, V.V....
Vector quantizers are known and are described generally in the publications: "An Algorithm for Vector Quantizer Design" by Y. Linde, A. Buzo and R. Gray in IEEE Trans. on communications, Vol. Com-28, No. 1, Jan. 1980 and in "Vector Quantization in Speech Coding" by J. Makhoul, S....
