  • Finite state machine-based trigger event detection employing interpolation
    Patent number: 9874863
    Abstract: Trigger event detection employs a finite state machine (FSM) and interpolation of time-sampled data. A trigger event detector includes an interpolator configured to interpolate time-sampled data and to provide an interpolated sequence of data. The trigger event detector further includes an FSM that has a plurality of predefined states including a trigger event state. The FSM is configured to transition among the predefined states according to an ordered sequence of symbols corresponding to the interpolated sequence of data. A transition of the FSM into the trigger event state represents detection of a trigger event. The trigger event detection provides one or both of a real-time trigger and a post-acquisition trigger.
