s] = 1 we have triangular pulse
with duration 2[[tau].
The extrapolated base width was 48 ns and the main motion of the waveform can be represented by a symmetrical triangular pulse
of 48-ns duration.
Although closed forms for rectangular and triangular pulses
have been computed in many books on Signals andSystems, however, we used a different approach here in obtaining the closed form expressions of these two pulses.
The electrical record shows two roughly triangular pulses
occurring about 2 milliseconds apart.
For example, the EI-signal considered in  is generated as a train of triangular pulses
with use of re-circulating cable loop.
