23. Let \( h(t) \) be the triangular pulse shown in Figure \( P 2.23(\mathrm{a}) \), and let \( x(t) \) be the impulse train depicted in Figure P2.23(b). That is, \[ x(t)=\sum_{k=-\infty}^{+\infty} \delta(t-k T) . \] Determine and sketch \( y(t)=x(t) * h(t) \) for the following values of \( T \) : (a) \( T=4 \) (b) \( T=2 \) (c) \( T=3 / 2 \) (d) \( T=1 \)
