An active pen 2 is configured to transmit one or more symbol values in one time slot, and includes a frequency dividing circuit 43 configured to frequency-divide a reference clock with a frequency division ratio based on each of a plurality of frequencies different from each other, to thereby generate a plurality of carrier waves having frequencies different from each other. The active pen 2 includes a modulation (transmission) circuit 44 configured to transmit a first downlink signal in a symbol duration that is common among the plurality of frequencies, the first downlink signal obtained by modulating a first carrier wave, which is among the plurality of carrier waves generated by the frequency dividing circuit 43, with a value of a first symbol that is a transmission target."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Active pen and sensor integrated circuit","description":"An active pen is provided, which facilitates avoiding complex computation for phase acquisition on the side of a sensor integrated circuit configured to receive downlink signals from active pens, and ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11972079","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.
