摘要
采用LabVIEW软件对脉冲编码调制中数字化量化进行了计算机模拟仿真,对均匀量化器和最佳非均匀量化做了简要介绍和对比,通过非均匀量化的仿真结果分析了量化误差引起的信噪比特性,为实际语音传输系统提供了基本的依据。
In this paper, the digital quantificalion of pulse code modulation was conducted by comlaoler simulation the software of LahVIEW. The uniform quantizer and optimal non-uniform quantization was briefly introduced c.ompared. The simulation resuh analysis of non-uniform quantization error caused by signal to noise ratio provided basis for the, real voice transmission system.
