Further, a first electrical filter apparatus is configured to receive the electrical digital communication signal, and comprises a low-pass filter having a cut-off frequency lower than the carrier frequency of the electrical analog radio signal, and applies the low-pass filter to the electrical digital communication signal. The apparatus also includes a signal combining apparatus configured to combine the low-pass filtered electrical digital communication signal with the electrical analog radio signal to form a combined electrical signal and an optical transmitter configured to generate an optical communication signal carrying a representation of the combined electrical communication signal."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Communication system multiplexing and demultiplexing apparatus and methods","description":"A communication signal multiplexing apparatus includes first and second optical receivers, with the second optical receiver configured to receive an optical analog radio signal and to convert it into ","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-11956015","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.
