Doublet

Block-library: DUBSI

Doublet creates a doublet signal.

The user must specify the following block-parameters:

• the initial value of the signal (= final value)
• the start time
• the length of the first time interval (Δt₁)
• the length of the second time interval (Δt₂)
• the top value
• the bottom value.

These block-parameters have been illustrated in the figure below:

The final value of the doublet-signal will always be equal to the initial value. In addition to the parameters mentioned above, the user must also specify whether the top value or the bottom value should come first. In the figure above, the default setting (top first) is shown. If 'bottom first' had been specified instead, the lowest value of the doublet signal would occur during the first time-interval and the highest value would occur during the second time-interval.

If the user inadvertently selects negative values for the time-intervals, the absolute value will be used instead, without any warning. If the user inadvertently selects a top value that is smaller than the bottom value, a warning message will be shown and both values will be swapped, to obtain at least a meaningful simulation result.
