WebZ-Transform is basically a discrete time counterpart of Laplace Transform. Z-transform of a general discrete time signal is expressed in the equation-1 above. The range of values of 'Z' for which above equation is defined gives ROC (Reason of Convergence) of Z-transform. ROC is the region of range of values for which the summation converges. WebApr 3, 2024 · By using chirped z-transform and unwrapping phase envelop function, the amplitude phase φ can be extracted from the monitor. We do partial derivative of the amplitude phase ∂ φ /∂ ω , and obtain the time delay τ d = ∂ φ /∂ ω .
