Solution Overview
Problem
Conventional oscilloscopes lack the ability to analyze each decoding step of the decoding process separately when decoding fails, making it difficult to identify and diagnose faults in data transmission.
Innovation Solution

Engineering Contradiction Analysis
1Reliability
If conventional oscilloscopes decode data signals using a single complete decoding process, then the decoding result is obtained, but the ability to analyze intermediate decoding steps is lost when decoding fails
Solution Approach 1:
The patent segments the complete decoding process into multiple individual decoding steps (e.g., step 1: detect rising/falling edges, step 2: detect data bits, step 3: detect data symbols, etc.). Each step produces an intermediate result that can be independently analyzed and labeled, allowing fault detection at specific decoding stages rather than only at the final result.
Solution Approach 2:
The patent performs preliminary labeling of intermediate decoding results at each step before proceeding to the next decoding step. Labels are assigned to intermediate results (such as signal edges, data bits, symbols) and mapped back to the original data signal, preserving information about each decoding stage for later analysis.
2Measurement precision
If detailed intermediate decoding results are recorded at each step, then fault analysis capability is improved, but the complexity of the decoding system increases
Solution Approach 1:
The patent introduces labels as intermediary elements that connect intermediate decoding results to the original data signal. These labels serve as a simplified representation of complex intermediate states, allowing precise tracking of decoding progress without requiring the system to maintain complex data structures for each intermediate result.
Solution Approach 2:
The patent creates simplified copies of intermediate decoding results in the form of labels that can be displayed and analyzed separately. Instead of processing and storing the full complexity of intermediate decoding states, the system generates label representations that capture the essential information needed for fault analysis.
3Measurement precision
If multiple decoding steps are analyzed separately, then the ability to identify specific fault locations is improved, but the time required for decoding analysis increases
Solution Approach 1:
The patent maintains continuous decoding operation by performing all decoding steps sequentially without interruption, while simultaneously generating and mapping labels for each intermediate result. This allows the system to complete the full decoding process while preserving analytical capability, rather than pausing to analyze each step individually.
Solution Approach 2:
The decoding system automatically generates and maps labels for intermediate results during the normal decoding process, without requiring separate manual analysis steps. The system serves its own analytical needs by integrating label generation into the decoding workflow, eliminating the need for additional external analysis time.
