离散时间信号(Discrete-time Signal)是指在时间上取离散值,幅度取连续值的一类信号,可以用序列(Sequence)来表示。 序列是指按一定次序排列的数值x(n)的集合,表示为: 注意:其中n为整数,x(n)表示序列,对于具体信号,x(n)也代表第n个序列值。特别应当注意的是,x(n)仅当n为整数时才有定义,对于非整数,x(n)没...

The comm.IntegrateAndDumpFilter System object creates a cumulative sum of the discrete-time input signal, while resetting the sum to zero according to a fixed schedule.
