\(v(t)=\dfrac{1}{T}r(t)+\dfrac{4}{T}r\!\left(t-\tfrac{T}{2}\right)+\dfrac{2}{T}r(t-T)\)

\(v(t)=\dfrac{2}{T}r(t)-\dfrac{4}{T}r\!\left(t-\tfrac{T}{2}\right)+\dfrac{2}{T}r(t-T)\)

\(v(t)=\dfrac{-2}{T}r(t)+\dfrac{4}{T}r\!\left(t-\tfrac{T}{2}\right)-\dfrac{1}{T}r(t-T)\)

\(v(t)=\dfrac{1}{T}r(t)-\dfrac{3}{T}r\!\left(t-\tfrac{T}{2}\right)+\dfrac{1}{3}r(t-T)\)
