Signal Parameter Highlighting in Oscilloscope Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current signal measuring devices, such as oscilloscopes, face inefficiencies in analyzing signal parameters over large time durations, as the track-function's variations are heavily compressed, making it difficult to identify abnormal behavior or regions of interest without a trial-and-error approach using the zoom-function.
Innovation Solution
A method and device for visually presenting signal parameters by buffering and displaying the signal on a display unit, determining parameters in multiple signal regions, and highlighting them in a graphical representation using color or contrast, allowing for direct identification of abnormal behavior without zooming.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If the track-function variations are displayed over large time durations, then the measurement time is extended, but the variations are heavily compressed making it difficult to identify abnormal behavior
Solution Approach 1:
The patent divides the displayed signal into multiple signal regions and determines signal parameters separately for each region. This segmentation allows the track-function to be presented in a compressed time scale while still providing detailed parameter information for individual regions, preventing information loss despite extended measurement duration.
2Measurement precision
If the zoom-function is used to obtain detailed information from the track-function plot, then the analysis precision is improved, but the analysis time increases due to trial-and-error approach
Solution Approach 1:
The patent performs preliminary determination of signal parameters for multiple signal regions before the user needs to analyze them. By pre-calculating and presenting parameter information for different time regions, the system eliminates the need for users to repeatedly zoom in and out to find abnormal behaviors, significantly reducing trial-and-error analysis time while maintaining precision.
3Device complexity
If the signal parameter is displayed in a separate diagram, then the signal representation is simplified, but the user cannot efficiently analyze the signal parameter over large time durations
Solution Approach 1:
The patent merges the signal display with the signal parameter presentation by determining parameters in multiple signal regions and displaying them within the signal representation itself. This integration allows users to efficiently analyze signal parameters over large time durations without requiring separate diagrams, thereby improving productivity while maintaining display simplicity.
