Quantization and Encoding Soutenance de thèse vendredi 24 novembre 2006, Lorient Lecture 5 Quantization and Encoding Analog-Digital Converter (ADC) An electronic integrated circuit which converts a signal from
The method apparently improves the performance of BAQ arithmetic during the saturation of ADC and can achieve the object by changing the quantization coding in FPGA only, without changing the software and hardware for BAQ arithmetic.祁海明禹卫东...
The general quantization process is shown in Fig. 3.2. Sign in to download full-size image Figure 3.2. Quantization process: Q represents the encoding or quantization stage and Q−1 represents the decoding or inverse quantization stage. Generally speaking, two kinds of quantization methods can ...
Such further encoding of the quantized source is called entropy coding. As no additional error or distortion is introduced, the error is that in the quantization alone. Therefore, with entropy coding, the distortion D and the entropy H are the important quantities of performance in the ...
Such a Product Quantization (PQ) technique has been used for compact encoding for approximate dis- tance computation in [1], and recently has also been adopted for building inverted indexing in [2]. When used for compact encoding, the time complexity is O(M k) per distance computation using...
Our design leverages the mixed-signal resistive random-access memory (RRAM) crossbar architecture in a novel dual-path configuration to realize basic NN operations at the circuit level and exploits smooth bit-encoding scheme to improve the training accuracy. Results obtained from SPICE simulations ...

Innovations in use of chroma quantization parameter ("QP") offsets when determining a control parameter for deblock filtering. For example, as part of encoding, an encoder sets a picture-level chroma QP offset and slice-level chroma QP offset for encoding of a slice of a picture. The ...
Third, the relationships among the saturation degree of the signal, the peak-topeak value of the ADC, standard deviation of the input and output signal of the ADC and the average signal magnitude are deduced. Based on these relationships, a power compensation decoder is designed ...
The sources of corruption include sampling and quantization effects as well as channel effects, as described in the following bulleted list. • Quantization noise: The distortion inherent in quantization is a roundoff or truncation error. The process of encoding the PAM waveform into a quantized ...
