0 0 votes The pole-zero diagram of a casual and stable discrete-time system is shown in the figure. The zero at the origin has multiplicity $4$. The impulse response of the system is $h[n]$. If $h[0]=1$, we can conclude $h[n]$ is real for all $n$ $h[n]$ is purely imaginary for all $n$ $h[n]$ is real for only even $n$ $h[n]$ is purely imaginary for only odd $n$ Continuous-time Signals gate2015-ec-1 continuous-time-signals poles-and-zeros + – Milicevic3306 463 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
