Parallel Frequency-Mask Trigger for Short Interference Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing frequency-mask trigger units struggle to detect short interference pulses in the time domain effectively due to limitations in sampling rate and processing speed.
Innovation Solution
A frequency-mask trigger unit comprising multiple trigger machines connected to an evaluation unit, where result vectors transformed into the frequency domain are compared in parallel with a threshold value, allowing for faster sampling and detection of short interferers by distributing the datastream across multiple machines and storing trigger statuses and timestamps for later analysis.

Engineering Contradiction Analysis
1Speed
If a single trigger machine processes the signal, then the device complexity is low, but the sampling rate and detection speed are insufficient to capture short interferers
Solution Approach 1:
The trigger machine is divided into n parallel trigger machines (where n≥2), each processing a separate signal path. This segmentation enables parallel processing of result vectors, increasing the effective sampling rate and detection speed while maintaining manageable complexity through modular architecture
Solution Approach 2:
The system transitions from sequential single-path processing to parallel multi-path processing by adding the dimension of parallel signal paths. Each trigger machine operates independently on its own signal path, transforming the processing architecture from one-dimensional sequential to multi-dimensional parallel operation
2Reliability
If the signal is sampled at the fastest possible rate, then short interferers can be detected, but the processing load on the computer increases significantly
Solution Approach 1:
The processing load is segmented and distributed across n trigger machines operating in parallel. Each machine handles a portion of the result vectors independently, dividing the overall processing complexity into manageable units while maintaining high sampling rates for reliable interferer detection
Solution Approach 2:
Each trigger machine autonomously evaluates result vectors against trigger ranges and generates trigger pulses independently without requiring centralized processing for every sample. This self-service capability reduces the processing burden on the main computer while ensuring reliable detection
3Reliability
If multiple trigger machines process signals in parallel, then the sampling rate increases and short interferers are detected securely, but the device complexity increases
Solution Approach 1:
The system is segmented into n independent trigger machines, each handling a specific signal path and result vector subset. This modular segmentation achieves reliable parallel processing while keeping individual machine complexity low and manageable
Solution Approach 2:
Each trigger machine is designed as a universal module capable of processing result vectors from its assigned signal path independently. This multi-functional design allows the same hardware architecture to be replicated n times, achieving parallel processing capability without increasing the complexity of individual units

AI summary
The frequency-mask trigger unit comprises n trigger machines, where n≥2, in order to evaluate a total of n signal paths. In this context, the n trigger machines are connected to an evaluation unit. For this purpose, at least one trigger range is transferred to the n trigger machines. Moreover, a plurality of result vectors of a signal under analysis transformed into the frequency domain are transferred via the n signal paths to the n trigger machines. Finally, each of the n trigger machines checks whether at least one of the plurality of result vectors of the signal under analysis transformed into the frequency domain infringes the at least one trigger range.
