词条 | Advanced z-transform |
释义 |
In mathematics and signal processing, the advanced z-transform is an extension of the z-transform, to incorporate ideal delays that are not multiples of the sampling time. It takes the form where
It is also known as the modified z-transform. The advanced z-transform is widely applied, for example to accurately model processing delays in digital control. PropertiesIf the delay parameter, m, is considered fixed then all the properties of the z-transform hold for the advanced z-transform. LinearityTime shiftDampingTime multiplicationFinal value theoremExampleConsider the following example where : If then reduces to the transform which is clearly just the z-transform of . References
