Behavior
y(t) = last accepted Boolean transition at or before t − delay. The worked example connects this operation to signals in Lemonergy Studio.

Boolean transport propagation delay — worked example
Delays accepted Boolean transitions while preserving their transport order.
- Boolean transport propagation delay: y(t) = last accepted Boolean transition at or before t − delay. The worked example connects this operation to signals in Lemonergy Studio.
- Use the block reference for settings and connections.
- Implementation tested locally; public release pending.
Connected concepts
Limits and interpretation
- Accepted Boolean transitions use a fixed positive timestamped transport delay and propagated boundaries. Inertial pulse suppression and dynamic propagation delay are not implemented.
- Shapes and element types are explicit. Values must be finite; automatic reshaping and unit conversion are not performed.
