Description: （一）基本任务：单频正弦波模拟信号的简单数字化。即对一个单频正弦波模拟信号进行抽样、均匀量化、PCM二进制自然编码。
1、主要步骤和要求：
（1）单频正弦波模拟信号的抽样实现。要求输入信号的幅度A、频率F和相位P可变；要求仿真时间从0到2/F，抽样频率为Fs=20F；要求给出抽样信号samp的波形图。
（2）单频正弦波模拟信号均匀量化的实现。要求对抽样信号sampl归一化后再进行均匀量化；要求量化电平数D可变；要求输出信号为平顶正弦波；要求给出量化输出信号quant的波形图，并与抽样信号samp画在同一图形窗口中进行波形比较。
（3）单频正弦波模拟信号PCM二进制自然编码的实现。要求按量化序号给出PCM二进制自然编码；要求给出编码后的数字序列pcm。

Description: 数字基带传输系统的MATLAB仿真实现
function [sampl,re_sampl]=system_1(A,F,P,D,snr,m,N)
输入变量A ,F,P分别为输入信号的幅度、频率和相位，D为量化电平数，snr
为信道信噪比，N为D/A转换时的内插点数；输出变量sampl为抽样后的输入
信号，re_sampl为恢复出的输入信号。
数字基带传输系统的MATLAB仿真实现
[sampl,quant,pcm]=a_d_1(A,F,P,D)
[changed_ami]=signal_encod_1(pcm)
[ami_after_channel]=channel_1(changed_ami,snr)
[adjudged_ami]=adjudg_1(ami_after_channel,m)
re_pcm=signal_decod_1(adjudged_ami)
[re_voltag,re_sampl,re_sampl1]=d_a_1(re_pcm,sampl,D,N)-Digital baseband transmission system implementation MATLAB simulation function [sampl, re_sampl] = system_1 (A, F, P, D, snr, m, N) input variables A, F, P, respectively, for the input signal amplitude, frequency and phase , D to quantify the number of electric-ping, snr for the channel signal to noise ratio, N to D/A converter when the interpolation points output variables for the sample after Sampl input signal, re_sampl for the restoration of the input signal. Digital baseband transmission system simulation MATLAB implementation [sampl, quant, pcm] = a_d_1 (A, F, P, D) [changed_ami] = signal_encod_1 (pcm) [ami_after_channel] = channel_1 (changed_ami, snr) [adjudged_ami] = adjudg_1 (ami_after_channel, m) re_pcm = signal_decod_1 (adjudged_ami) [re_voltag, re_sampl, re_sampl1] = d_a_1 (re_pcm, sampl, D, N)
