Z-transform of unit step sequenceSolution : The definition of unit step sequence is \[u_n=1 if n=0,1,2,3,….0 if n=-1,-2,-3,…\] We know that Z-transform of a signal yn is given as \[Z\left(y_n\right)=\sum_{n=0}^{\infty}{y_nz^{-n}}\] Therefore Z-transform of unit step sequence is \[Z\left(u_n\right)=\sum_{n=0}^{\infty}{u_nz^{-n}}\] using definition…
