A first phase of the first signal detected on the second electrodes is determined. A second phase of the second signal detected on the first electrodes is estimated based on the first phase and a portion of the first signal associated with the second phase is extracted. Coordinates of a handheld device is determined based on the portion of the first signal extracted from the first electrodes and the second signal and the coordinates are reported to a host computing device associated with the digitizer sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Noise reduction in a digitizer system","description":"A method includes detecting a first signal on first electrodes along a first axis of a digitizer sensor, detecting a second signal on second electrodes along a second axis of the digitizer sensor, det","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9823774","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.
