# Relation between impulse response and Region of convergence?

Is there any relation between impulse response and Region of convergence?Means position/location of ROC depends upon impulse response or not??

• There is connection between transforms of the impulse response and their ROC and the corresponding impulse response. Are we talking about discrete time or continuous time? – GKH Feb 24 at 16:35
• "the corresponding impulse response" which impulse response is this?? – engr Feb 24 at 16:52
• I mean, an impulse response has a transform, a represenation in another domain (complex frequency, in general). The ROC of the transform is connected to the form of the impulse response. – GKH Feb 24 at 19:46

For all FIR (finite inpulse response) systems, the ROC will be all $$z$$ except possibly zero and/or infinity.
