Chapter 2
- Unit step $$u(t)$$
- $$u(at)=u(t)$$
- Unit ramp ramp($$t$$)=$$r(t)$$=$$t\,u(t)$$
- $$r(at)=at\,u(at)=at\,u(t)=a\,r(t)$$
- Unit rectangle rect($$t$$)=$$u(t+1/2)-u(t-1/2)$$
- rect($$t/a$$) has a centered pulse of height 1 and width $$a$$
- Unit triangle tri($$t$$)=$$r(t-1)-2r(t)+2(t+1)$$
- tri($$t/a$$) is a centered triangle of width $$2a$$ that peaks at a height of 1
