If the signal $x[n]=(2.0)^{\mid n\mid},-\infty<n<+\infty$, then the ROC of its $z$-transform is represented by Numerical Methods gate2016-ec-3 numerical-methods convergence-criteria + – Milicevic3306 asked Mar 27, 2018 • retagged Mar 1, 2021 by Lakshman Bhaiya Milicevic3306 16.0k points 126 views answer comment Share Follow See all 0 reply Please log in or register to add a comment.
