Consider the signal $x(t)?\mathrm{sgn}(t)p(t;?1,1)$. Part (a) $[10$ points $]$ Express $x$ as the weighted sum of shifted step signals using the table method. Part (b) $[10$ points $]$ Compute and graph the signal $y(t)?D\{x(t)\}$. Part (c) $[10$ points $]$ Provide the block diagram of a system consisting of elementary subsystems, such as time shifts, integrators, etc., whose impulse response is the signal $x$.
