The block implements a JK-trigger model with a synchronizing input C, i.e. when the signal at the input C drops, the block works similarly to the RS-trigger with one difference: when a logical 1 is supplied to both inputs J and K, the state of the trigger output changes to the opposite.
The truth table of the JK-trigger during a signal drop at input C is presented below.
| J | K | y(t) |
|---|---|---|
| 0 | 0 | y(t–Δt) |
| 0 | 1 | 0 |
| 1 | 0 | 1 |
| 1 | 1 | y̅(t–Δt) |
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 state regardless of the signal values at the J and S inputs.
Входные порты
- J – the setting input port;
- C – the input synchronization port;
- K – the resetting input port.
Выходные порты
- out – trigger output port;
- Yinv – an inverse output port (optionally included in the block properties).
Свойства
- Initial conditions – initial condition of the output;
- Add inverse output – adds an additional inverse output port.
