Sketch the following CT functions. 

(a) \(x(t)=8 u(5-t)\); 

(b) \(x(t)=3 \delta(t+2)\); 

(c) \(x(t)=\operatorname{ramp}(t+1)\); 

(d) \(x(t)=5 \operatorname{rect} \frac{(t+1)}{4}\); 

(e) \(x(t)=-\operatorname{tri} \frac{t-1}{4}\); 

(f) \(x(t)=\) \(u(t)-u(t-5) 

{g} x(t)=u(t)-u(t+5) ;(\mathrm

(h) x(t)=-\operatorname{ramp}(t) u(t-3)\); (i) \(x(t)=u(t)\left(t+\frac{1}{3}\right) \operatorname{ramp}\left(\frac{1}{3}-t\right) ;(\mathrm{j}) x(t)=\operatorname{rect}(t+2)-\operatorname{rect}(t-2)\).
