此用since。

18. 选A。在他们一起走的时候，Mark得知这个孩子叫Bill，……。B有一定的干扰性，realize

1.通信的目的是传输消息中所包含的息。消息是信息的物理表现形式，信息是消息的有效内容。.信号是消息的传输载体。

2.根据携载消息的信号参量是连续取值还是离散取值，信号分为模拟信号和数字信号．，

3.通信系统有不同的分类方法。按照信道中所传输的是模拟信号还是数字信号（信号特征分类），相应地把通信

系统分成模拟通信系统和数字通信系统。按调制方式分类：基带传输系统和带通（调制）传输系统。

4.数字通信已成为当前通信技术的主流。

5.与模拟通信相比，数字通信系统具有抗干扰能力强，可消除噪声积累；差错可控；数字处理灵活，可以将来自不同信源的信号综合刭一起传输；易集成，成本低；保密性好等优点。缺点是占用带宽大，同步要求高。

6.按消息传递的方向与时间关系，通信方式可分为单工、半双工及全双工通信。

7.按数据码先排列的顾序可分为并行传输和串行传输。 8.信息量是对消息发生的概率（不确定性）的度量。

9.一个二进制码元含1b的信息量；一个M进制码元含有log2M比特的信息量。等概率发送时，信源的熵有最大值。

10.有效性和可靠性是通信系统的两个主要指标。两者相互矛盾而又相对统一，且可互换。在模拟通信系统中，有效性可用带宽衡量，可靠性可用输出信噪比衡量。

38.crazy

39.

11.在数字通信系统中，有效性用频带利用率表示，可靠性用误码率、误信率表示。

12.信息速率是每秒发送的比特数；码元速率是每秒发送的码元个数。

13.码元速率在数值上小于等于信息速率。码元速率决定了发送信号所需的传输带宽。

第二章

14.确知信号按照其强度可以分为能量信号和功率信号。功率信号按照其有无周期性划分，又可以分为周期性信号和非周期性信号。

15.能量信号的振幅和持续时间都是有限的，其能量有限，（在无限长的时间上）平均功率为零。功率信号的持续时间无限，故其能量为无穷大。

16.确知信号的性质可以从频域和时域两方面研究。

17.确知信号在频域中的性质有4种，即频谱、频谱密度、能量谱密度和功率谱密度。

18.周期性功率信号的波形可以用傅里叶级数表示，级数的各项构成信号的离散频谱，其单位是V。

19.能量信号的波形可以用傅里叶变换表示，波形变换得出的函数是信号的频谱密度，其单位是V/Hz 。

20.只要引入冲激函数，我们同样可以对于一个功率信号求出其频谱密度。

21.能量谱密度是能量信号的能量在频域中的分布，其单位是J/Hz。功率谱密度则是功率信号的功率在频域中的分布，其单位是W／Hz。

22.周期性信号的功率谱密度是由离散谱线组成的，这些谱线就是信号在各次谐波上的功率分量|Cn|2，称为功率谱，其单位为w。但若用δ函数表示此谱线。则它可以写成功率谱密度|C（f）|2δ（f-nf0）的形式。

23.确知信号在时域中的特性主要有自相关函数和互相天函数。 24.自相关函数反映一个信号在不同时间上取值的关联程度。 25.能量信号的自相关函数R(O)等于信号的能量；而功率信号的自

相关函数R(O)等于信
