求翻译：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。是什么意思？

In the discrete-time signal analysis and processing, often added to the sequence, multiply, and other computing delay and convolution, z transforms useful features to simplify operation.

In discrete time signals in the analysis and processing, often carried out in sequence, multiplied by 175, delay and Convolve such calculations, and Z transforms the character is very useful to simplify calculations.

In the discrete time signal analysis and processing, must carry on operations frequently and so on adding together, multiplication, time delay and convolution to the sequence, the z transformation characteristic is extremely useful regarding the simplification operation.

In the discrete-time signal analysis and processing, often to add, multiply your sequence, delay and convolution operation, z transform properties are useful for simplifying operation.

In the discrete-time signal analysis and processing, often added to the sequence, multiply, and other computing delay and convolution, z transforms useful features to simplify operation.
