1.把信号只在某些不连续的瞬时给出函数值,成为离散时间信号.它可以来自模拟信号的抽样,或者是时间和幅度均不边续的离散信号.在离散信号的分析和处理时,通常把按一定先后次序排列在时间上不连续的一组数的集合,称之为”序列”.
2.两个不同的序列可以对应相同的Z变换,而收敛域并不相同,因此,为了使序列和Z变换是一一对应,在给出序列Z变换的同时,必须指定其收敛域.
3.在离散时间信号的分析和处理中,常常要对序列进行相加,相乘,延时和卷积等运算,Z变换的特性对于简化运算非常有用.

1. Signal only in certain discrete function of the instantaneous value is as discrete-time signal. It analog signal from the sample, or is not the time and the magnitude of the added edge discrete signal.Discrete signal analysis and processing, usually by a certain time in order not for a group of pool called "sequence."
2. Two different sequences can be the same as the corresponding Z transform, and the convergence domain is not the same, therefore, To sequence and Z transform is uniquely presented in sequence Z transform, we must designate their convergence domain.
3. In discrete-time signal analysis and processing, often to the sequence together, multiply, and delay operations such as convolution, Z-transform the properties for simplified operation very useful.

离散时间信号在时间上离散,为什么在幅度上却是连续的?
在数字计算机上处理的信号是模拟信号、离散时间信号还是数字信号?
书上说“如果离散时间信号的幅值是连续的,则又可称之为抽样信号”.
数字电路与逻辑设计2数字信号和模拟信号的不同之处是数字信号在大小上不连续,时间上连续,而模拟信号则相反.正确 错误 (6
离散信号 抽样信号 数字信号的区别
谁能举例告诉一下,1.时间离散、数值连续信号 2.时间连续、数值离散的信号.
.把连续时间信号进行离散化时产生混迭的主要原因是
模拟信号的时域抽样能保证不失真,离散信号的频率抽样能保证不失真么?
离散信号的幅值为什么可以是连续的啊?时间不是离散的吗?按理说幅值离散才对啊.
离散时间信号与数字信号的区别
为什么离散时间信号的频谱是周期的?
