τ = 3/4

, the reflected pulse dominates the overlap. The total displacement is zero outside

[- 3/4, 0]

and consists of straight segments through

(u, y / H) = (- 3/4, 0), (- 1/4, - 1), (0, 0) .

This is the inverted version of the quarter-reflected profile. The entire negative pulse has not yet separated from the incident pulse.
