DSP[6] Flashcards
Is a mathematical tool commonly used for the analysis and synthesis of discrete-time control systems.
Z transform
Is the most generated concept for the transformation of discrete-time series.
Z transform
Is the most generated concept for the transformation of continuous time processes
Laplace transform
Laplace transform worked on rectangular coordinates, whereas z transform work in ______
Polar coordinates
Z transform reduces to the fourier transform when the magnitude of the transform variable z is
Unity
The region of convergence is bounded by
Poles
means a bounded input will not yield on unbounded output
Stable System
is one in changes in output do not precede changes in input
Causal system
If ROC includes the unit circle, then the system is
Bounded input, bounded output(BIBO) stable
If the ROC extends onward from the pole with the largest (but not infinite) magnitude, then the system is
Right-sided impulse response
If the ROC extends onward from the pole with the largest magnitude and there is no pole at infinity, then the system is
Causal
If the ROC extends onward from the pole with the smallest (non-zero) magnitude, then the system is
Anti-causal
If you need stability then the ROC must contain
The Unit circle
If you need causal system then the ROC must contain
Infinity and the system function will be right-sided sequence
If you need anti-causal system then the ROC must contain
The origin and the system finction will be a left-sided sequence
