收敛域英文

1st, only gives the function value the signal in certain not continual instants, becomes the discrete time signal. It may come from the simulated signal sampling, or is the time and the scope not continual discrete signal. When discrete signal analysis and processing, usually presses certain priority order to arrange in the time not a continual number of classes set, calls it the sequence. 2, two different sequences may correspond the same Z transformation, but the convergence domain is not same, therefore, to cause the sequence and the Z transformation is 11 correspondences, while gives the sequence Z transformation, must assign its convergence domain. 3, the random signal cannot use the precise mathematics relationship description the signal, but its change obedience statistics rule, may use the probability statistical property to describe. Each vice minister who does according to the time course the time observation record is called the sample function immediately to the signal. 4, random signal's time domain and the frequency range characteristic may use the statistical method to conduct the research, its peak-to-peak value characteristic uses the signal the average value, the mean square value and the probability density function expression. The signal time domain characteristic may also use the autocorrelation function to describe, the frequency range characteristic may use the power spectral density function to describe

1, a signal being put up the function value only in some discontinuous microtime , becomes straggling time signal. It can come from the analog signal sampling , be time and without exception discontinuous extent scattering signal or. During the period of scattering signal analysis and treatment , generally with arranging aggregation mounting discontinuous group of number in time according to certain precedence , being called progression. Different 2, two arrays can be corresponding identical Z varies, but the convergence region is not same as, therefore, for making the array and Z vary is one to one correspondence, must assign the person to restrain self's a region while giving array Z out alternation. The random signal can use the signal that accurate mathematics relational expression describes 3, its alteration obedience counts but a law , can use probability statistics to describe that coming characteristic property. The signal is called the sample book function face to face immediately according to precis writer made by time course. Random signal time domain and frequency region characteristic property can use statistical method to be in progress studying 4, whose amplitude characteristic property uses the signal mean value , mean square value and probability density function indicate that. Signal time domain characteristic property also can use self relevance function to describe that , frequency region characteristic property can use power spectrum density function to describe that.

不是。Z变换（英文：z-transformation）可将时域信号（即：离散时间序列）变换为在复频域的表达式。它在离散时间信号处理中的地位，如同拉普拉斯变换在连续时间信号处理中的地位。双边z变换的收敛域不是一定大于1。根据Z变换的定义可知,Z变换收敛的充要条件是它满足绝对可和条件。

个人认为：函数项级数的存在域也就是函数项级数的收敛域,是使函数项级数收敛的所有收敛点的集合. 英文名称及定义也可以参考函数项级数的收敛域的英文名称和定义
