 # Ramps

 Last update: 16.07.2025 

The flow is the sequence of an array of ramps. Each ramp is defined by a duration, an amplitude, and an offset. The time sample is common to all the ramps.

The figure shows the output flow for a sequence of 3 ramps with the following inputs:

- durations: \[1., 3., 1.\]
- ts (timesample): 0.2
- amplitudes: \[1.8, -1.4, 1.0\]
- offsets: \[-0.8, 1.0, -0.4\]
