Also known as unilateral Z transform, Z transform, one-sided Z-transform
In mathematics and signal processing, the Z-transform converts a discrete-time signal, which is a sequence of real or complex numbers, into a complex valued frequency-domain (the z-domain or z-plane) representation.

在數學和信号处理中，Z轉換（英語：Z-transform）把一連串離散的實數或複數訊號，從時域轉為复頻域表示。 可以把它认为是拉普拉斯变换的离散时间等价。在时标微积分中会探索它们的相似性。
