Signal Level Indicator Layout for Reference Matching Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing signal processing devices cannot effectively allow users to check the degree of difference between the signal level and the reference level when the indicator is not lit, making it difficult for users to adjust the signal level accurately.
Innovation Solution
A signal processing device with an input part, storage, amplification part, adjustment part, and display that shows specific and non-specific display results based on the relation between the setting value and reference value, using indicating lamps to indicate when the signal level matches the reference level.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If an indicator lights up only when the signal level matches the reference level, then the user can recognize when adjustment is complete, but the user cannot check the degree of difference when the indicator is off
Solution Approach 1:
The indicator is divided into multiple segments (e.g., 10 segments) that light up progressively as the signal level approaches the reference level. Each segment represents a specific degree of difference, allowing users to see both when matching is complete (all segments lit) and the current degree of difference (number of lit segments) at any adjustment stage.
Solution Approach 2:
The indicator uses different colors or brightness levels to represent different degrees of difference between signal level and reference level. For example, the indicator may display green when matched, yellow when close, and red when far from matching, providing intuitive visual feedback about the adjustment progress and degree of difference.
2Adaptability or versatility
If multiple scales are arranged on the front panel for multiple targets, then each target can be monitored, but the display becomes complicated and design is degraded
Solution Approach 1:
A single indicator serves multiple functions by displaying different information for multiple targets sequentially or simultaneously. The indicator can be switched between different targets or channels, or can display composite information about multiple targets, eliminating the need for separate scales for each target while maintaining multi-target monitoring capability.
Solution Approach 2:
Multiple scale functions are merged into a single indicator display. The indicator integrates the monitoring of multiple targets by displaying their status collectively or allowing rapid switching between targets, combining what would traditionally require multiple separate scales into one unified display element.

AI summary
The present invention provides a signal processing device that allows a user, who adjusts a signal level to match a reference level, to adjust the signal level while checking a degree of difference between the signal level and the reference level.A signal processing device according to the present invention comprises: an input part 20 to which an input signal is input; a storage 40 that stores therein one or more setting values of a parameter to be used for amplifying the input signal and a reference value of the setting value; an amplification part 30 that generates an output signal by amplifying a level of the input signal based on the setting value; an output part 70 that outputs the output signal; an adjustment part 50 that adjusts the setting value; and a display 60 that displays a display result determined based on the setting value adjusted by the adjustment part and the reference value. The display result displayed on the display 60 includes: a specific display result displayed when a relation between the setting value and the reference value is a specific relation; and a non-specific display result displayed when the relation between the setting value and the reference value is different from the specific relation.
