The block implements a D-trigger model with a synchronizing input C, which transmits data from input D to output at the time of synchronization, depending on the type of synchronizing input:
- by the front – when changing the value at the synchronizing input from 0 to 1;
- by the drop – when changing the value at the synchronizing input from 1 to 0;
- by the front and drop – in case of any change in the value at the synchronizing input;
- by level – when a logical one is supplied to the synchronizing input (data from input D will be transmitted to the output at each step of integration).
The truth table of the D-trigger at the time of synchronization is presented below.
| D | y(t–Δt) | y(t) |
|---|---|---|
| 0 | 0 | 0 |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | 1 |
where y(t-Δt) and y(t) are the output signals of the block at the previous and current integration steps, respectively.
Otherwise, the block saves the previous output condition regardless of the value at input D.
Входные порты
- D – the input data port;
- C – the input synchronization port.
Выходные порты
- out – trigger output port;
- YINV – the inverse output port (optionally activated in the block properties).
Свойства
- Synchronization input type – condition of triggering the synchronization input;
- Initial conditions – initial condition of the output;
- Add inverse output – adds an additional inverse output port.
