Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If present measurement instruments (oscilloscopes, spectrum analyzers) are used to measure jitter, then jitter can be measured as an overall distribution, but the jitter components (random jitter, periodic jitter, cycle jitter, inter-symbol interference) cannot be separated and analyzed individually
Solution Approach 1:
The patent segments jitter measurement into distinct components (random jitter, periodic jitter, cycle jitter, inter-symbol interference) by implementing separate analysis modules for each component. The measurement system divides the overall jitter signal into individual jitter types that can be analyzed independently, allowing precise characterization of each jitter source while maintaining a unified measurement platform.
2Adaptability or versatility
If spectrum analyzers are used to measure jitter, then jitter values can be obtained, but the periodic jitter and random jitter cannot be separated, and the instruments cannot analyze simulation signals in document formats
Solution Approach 1:
The patent creates a universal jitter analysis platform that can process multiple signal formats (measurement signals from oscilloscopes and simulation signals from document files) through a single integrated system. The measurement instrument incorporates multiple analysis functions including time-domain and frequency-domain analysis, enabling it to handle diverse signal sources while maintaining precise jitter component separation through its modular architecture.
3Loss of information
If comprehensive jitter component analysis is implemented to separate random jitter, periodic jitter, cycle jitter, and inter-symbol interference, then detailed jitter understanding is achieved, but the measurement system complexity increases
Solution Approach 1:
The patent segments the complex jitter analysis task into distinct functional modules, each responsible for a specific jitter component or analysis type. This modular segmentation allows the system to provide comprehensive jitter component information (random, periodic, cycle jitter, inter-symbol interference) while managing system complexity through organized, independent analysis units that can be selectively activated.
Solution Approach 2:
The patent introduces intermediary processing layers that facilitate the separation and analysis of different jitter components. These intermediary modules act as mediators between the raw jitter signal and the final analysis results, organizing the complex measurement data into structured component information through intermediate processing steps that simplify the overall system architecture.
