  • Apparatus for detection of a leading edge of a photo sensor output signal
    Patent number: 8446308
    Abstract: A system and method for processing an analog signal output by a sensor. The system and method converting, using at least one analog-to-digital converter (ADC), the analog output signal to a digital signal, the digital signal including a plurality of samples at a predetermined resolution, detecting whether a trigger condition is met by analyzing the digital signal, detecting an event based on trigger information from the detecting whether a trigger condition is met, generating event information having time information included therein when the event is detected, defining one or more time windows based on the time information included in the event information, performing decimation on the digital signal based on the defined one or more time windows to generate a decimated signal, and outputting the decimated signal.
