GATE ECE 2004 | Question: 19
The impulse response $h[n]$ of a linear time-invariant system is given by \[h[n]=u[n+3]+u[n-2]-2 u[n-7]\] where $u[n]$ is the unit step sequence. The above system is stable but not causal stable and causal causal but unstable unstable and not causal

GATE ECE 2004 | Question: 21
The $z$-transform of a system is $H(z)=\frac{z}{z-0.2}.$ If the ROC is $|z|<0.2$, then the impulse response of the system is $(0.2)^{n} u[n]$ $(0.2)^{n} u[-n-1]$ $-(0.2)^{n} u[n]$ $-(0.2)^{n} u[-n-1]$
The $z$-transform of a system is $H(z)=\frac{z}{z-0.2}.$ If the ROC is $|z|<0.2$, then the impulse response of the system is$(0.2)^{n} u[n]$$(0.2)^{n} u[-n-1]$$-(0.2)^{n}...
