PCM
说明: 利用Matlab仿真脉冲编码调制(PCM)及A律、μ律PCM对声音进行压缩编解码过程。
脉冲编码调制(PCM,Pulse Code Modulation)是一种将模拟语音信号转换成数字信号的编码方式。波形编码器的作用是对采样后的信号样本进行量化和编码。从数学上来看,量化过程就是把一个连续幅度值的无限数集合映射成一个离散幅度值的有限数集合,编码就是用一组二进制数来表示这些映射后的有限数。国际标准化的PCM采用折叠二进制码,符合长途电话质量。根据量化方法的不同,PCM可分为均匀量化PCM和对数PCM两大类,对数PCM中,2Aμ律和律编码都已被定为国际标准。(Matlab simulation using pulse code modulation (PCM) and the A law, μ law PCM codec for voice compression process.
Pulse Code Modulation (PCM, Pulse Code Modulation) is an analog voice signal into digital signal encoding. The role of the encoder waveform is sampled signal sample quantization and coding. From the mathematical point of view, the process is to quantify the magnitude of the value of a continuous set of infinite number of maps into a finite number of discrete set of amplitude values , encoding is to use a set of binary digits, said after a limited number of these maps. By folding the International Standardization of PCM binary code, in line with long-distance telephone quality. According to the different quantitative methods, PCM can be divided into uniform quantization PCM PCM and the number of two categories, on the number of PCM in, 2Aμ law and legal codes have been designated as international standards.)
