ADPCM DECODERPURPOSE: To prevent a large amplitude change from being generated at an analog output even when a value obtained by accumulating a differential value is over the output range of a D/A converter, at the time of decoding an ADPCM code.TOFUKU SUKEYUKI...
CONSTITUTION:An ADPCM signal is released of coding by an ADPCM decoding circuit 104 and becomes a linear PCM signal. then the signal is outputted at the outside of an LSI 100 via a terminal 108 or fetched from the outside of the LSI 100 via a terminal 110. A switch circuit 106 ...

本压缩包中的"adpcmdecoder"项目包含C++源代码,提供了以下功能: 1. PCM转G711:这涉及到将PCM数据通过μ-law或A-law算法进行编码,生成符合G711标准的数据流,可用于电话网络传输。 2. G711转PCM:这个过程是G711编码的逆操作,将接收到的G711数据解码回原始的PCM格式。 3. ADPCM转PCM:将采用ADPCM编码的音频数据...
PURPOSE: To decode a source sound faithfully by preventing an analog output from having large amplitude variation even when the value obtained by accumulating difference values exceeds the output range of a DA converter 8 when ADPCM codes are decoded. ;CONSTITUTION: The ADPCM code data in an L ...
An ADPCM encoder and decoder includes an adaptive quantizer and an adaptive predictor. A quantizing-step-size adaptation circuit determines a quantizing-step-size for the adaptive quantizer in dependence upon the ADPCM signal. When the q... PE Chow,AH Weirich,L Strawczynski - US 被引量: 40...
