1 1 vote The $Z$-transform of $\{x(n)\}$ is defined as $X(z)=\sum_{n} x(n) z^{-n}$ (for those $z$ for which the series converges). Let $u(n)=1$ for $n \geq 0$ and $u(n)=0$ for $n<0$. The inverse $Z$-transform of $X(z)=$ $\log (1-a z),|z|<1 / a$ is $a^{n} u(n-1) / n$ $a^{-n} u(-n-1) / n$ If $|a|<1$, then the answer is (a), otherwise the inverse is not well-defined If $|a|<1$, then the answer is (b), otherwise the inverse is not well-defined None of the above Discrete-time Signals tifr2013 z-transform discrete-time-signals + – admin 329 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
