Duty Timing Detector for Toggle Signal

The patent introduces a duty timing detector as an intermediary device that receives the toggle signal and generates detection voltages at specific timing points (e.g., 1/4, 1/2, 3/4 duty cycles). This intermediary detector enables timing observation without directly modifying the toggle signal generation, thus adding detection capability while maintaining relative simplicity in the overall system architecture.

The patent replaces potential mechanical or complex electronic timing detection methods with an electronic circuit-based duty timing detector that uses voltage generation and comparison techniques. The detector uses electronic components to generate sawtooth voltages and compare them with reference voltages, substituting simpler electronic mechanisms for more complex alternative approaches.

The duty timing detector divides the toggle signal duty cycle into multiple segments by generating detection voltages at different timing points (1/4, 1/2, 3/4 duty cycles). This segmentation allows accurate timing detection at multiple critical points within the duty cycle without requiring a single complex detection mechanism, thereby improving measurement precision while keeping the device structure manageable through modular voltage generation stages.

The patent changes the voltage parameter dynamically during the duty cycle by generating sawtooth voltages that increase linearly with time and comparing them against reference voltages. This parameter change approach (voltage level progression) enables precise timing detection by identifying when specific voltage thresholds are crossed, achieving high measurement accuracy through simple voltage comparison operations rather than complex timing circuitry.
