The horizontal axis plots time t in nanoseconds, ranging from 1 to 12 in increments of 1 while vertical axis plots voltage V sub L, ranging from negative 4 to 6 V in increments of 2. The graph plots a line which runs along the horizontal axis from 0 to 2 nanoseconds, then steps up to 6 V between 2 and 3 nanoseconds before dropping down to 0 between 3 and 6 nanoseconds. The line then steps down to negative 1.8 volts between 6 and 7 nanoseconds before stepping up to 0 between 7 and 12 nanoseconds, while briefly stepping up to 0.54 volts between 10 and 11 nanoseconds.
