A system is excited by a signal \( \mathrm{x}(t)=4 \operatorname{rect}(t / 2) \) and its response is \[ \mathrm{y}(t)=10\left[\left(\mathrm{l}-e^{(t+1)}\right) \mathrm{u}(t+\mathrm{l})-\left(\mathrm{l}-e^{(t-1)}\right) \mathrm{u}(t-1)\right] \] What is its impulse response of the system in time domain?
