脉冲编码调制(PCM)实现
编程实现PCM技术的三个过程:采样、量化与编码。
采样:低通连续信号采样,以 x=sin(200*t) m=x./(200*t) m=m.*m 为例说明低通采样定理,绘出信号时、频图形;带通连续信号采样,以x=sin(20*t) m=x./t 为例说明带通采样定理,绘出信号时、频图形。
量化:均匀量化,以幅度 的正弦信号为例实现为64级电平的均匀量化;非均匀量化,输入A律PCM编码器的正弦信号 ,采样序列为 ,将其进行PCM编码,给出编码器的输出码组序列
编码:以上述信号为例,实现A律的13折线近似法及国际标准PCM对数A律量化编码。(Pulse code modulation (PCM) to achieve
PCM technology programming three processes: sampling, quantization and coding.
Sample: low-pass continuous signal sampling to x = sin (200* t) m = x./(200* t) m = m.* m an example low-pass sampling theorem, draw the signal, frequency graphics bandpass sampling continuous signals to x = sin (20* t) m = x./t an example bandpass sampling theorem, draw the signal, frequency graph.
Quantization: uniform quantization, in order to realize the magnitude of sinusoidal signal as an example for the 64 level uniform quantization non-uniform quantization, input A law PCM encoder sine signal, the sampling sequence, to be PCM encoded, the encoder is given The output code sequence
Code: A Case Study of the signal to achieve the 13 A line approximation law and international standards on the number of A law PCM coding quantization.)
