The filter device includes a summing element (510-51N, 610) connected to a correction element (540, 640). The summing element (510-51N, 610) sums the input signal (Cα(t), Cα[k]) within a reference interval (N) and the correction element (540, 640) verifies the summed input signal (IS[k]) with at least one signal condition (0, N+1, ΔCα[k]). Finally, the correction element (540, 640) outputs a predetermined signal (Cαα[k]) based on the result of the verification between the summed input signal (IS[k]) with at least one signal condition (0, N+1, ΔCα[k]). The foregoing filter device is able to remove noise from an input signal. This stabilizes the input signal against environmental influences occurring e.g. during signal transmission."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Filter device for detecting and/or removing erroneous components in and/or from a signal","description":"The invention relates to a filter device (341, 342) for detecting and/or removing erroneous components like noise, deformations, glitch components or other errors in and/or from a signal, to a demodul","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-8472909","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
