The differential mode device is connected to a first output line of the pair of output lines of a first transformer exclusive of connection to a second output line of the first transformer. The differential mode device is configured to inject a signal from the first output line onto the pair of output lines of a second transformer. Signals from the pair of output lines of the second transformer are injected onto a pair of conductors, respectively, of a communications medium."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Electrical device for multiple-signal injection onto multiple-conductor communications medium","description":"An electrical device includes signal ports, transformers, and a differential mode device.
