从均匀PCM方法入手，产生一振幅为1和频率ω=1的正弦信号，分别用8电平和16电平进行量化，在同一坐标轴上绘出原信号和以量化信号，并比较这两种情况下的信号/量化噪声比-Starting from the uniform PCM method to produce a 1 amplitude and frequency ω = 1 of the sinusoidal signal, respectively, with 8 levels and 16 levels were quantified

产生一个幅度为1，频率为w=1的正弦序列，采用均匀PCM方案，将其进行8级量化和16级量化，在同一坐标系内绘出原始信号和量化信号的曲线，并计算量化的S/N-Generating an amplitude of 1 and a frequency of the sinusoidal sequence w = 1, the uniform PCM scheme, which is carried out 8 and 16 quantization quantization, the original
