Debouncers

Filter out the oscillation of transient signals

Debouncing logic filters out transient signals that do not represent a true change of state. Simplify your debouncer design by using the duration operator. For advanced filtering techniques, such as fault detection, use intermediate graphical states.

Featured Examples

View Sequential Logic Through State Transition Matrix

Use the State Transition Matrix view for a state transition table in Stateflow®. Instead of drawing states and transitions graphically in a Stateflow chart, use state transition tables to express the modal logic in tabular format. State transition tables are supported only as blocks in a Simulink® model. For more information, see State Transition Tables in Stateflow.

Implement an Automatic Transmission Gear System by Using the duration Operator

Models an automotive transmission system by using the Stateflow® temporal logic operator duration to automatically shift gears based on the vehicle throttle requirements and speed. For more information, see Control Chart Execution by Using Temporal Logic.
