1 1 vote Two systems $H_1(z)$ and $H_2(z)$ are connected in cascade as shown below. The overall output $y(n)$ is the same as the input $x(n)$ with a one unit delay. The transfer function of the second system $\mathrm{H}_2(z)$ is $\frac{\left(1-0.6 z^{-1}\right)}{z^{-1}\left(1-0.4 z^{-1}\right)}$ $\frac{z^{-1}\left(1-0.6 z^{-1}\right)}{\left(1-0.4 z^{-1}\right)}$ $\frac{z^{-1}\left(1-0.4 z^{-1}\right)}{\left(1-0.6 z^{-1}\right)}$ $\frac{\left(1-0.4 z^{-1}\right)}{z^{-1}\left(1-0.6 z^{-1}\right)}$ Discrete-time Signals gate2011-ec discrete-time-signals transfer-function digital-circuits + – admin 359 views answer comment Share Follow Add Sync Questions Print 0 reply Please log in or register to add a comment.
