Abstract: Disclosed is an interface device capable of simultaneously connecting an audio device and charger to an electronic device. An interface device may enable an electronic device with a single USB type-C connector but no analog audio jack to connect to both an audio device and a charger through the USB type-C connector. The interface device may provide automated quick charging when connected with the charger but not with the audio device.

Abstract: An electronic device and a method for changing modes according to external devices connected through a universal serial bus (USB) and controlling the strength of signals communicated according to changed modes are provided. The method includes detecting a connection with an external device corresponding to booting of the electronic device, determining a mode of the electronic device according to the detected connection with the external device, varying a characteristic setting of an input output (IO) buffer to a certain strength corresponding to the determined mode, and communicating a signal at a strength corresponding to the varied setting.

Abstract: The present disclosure relates to an improvement in the quality of a transmitted signal, and more particularly, to an electronic apparatus and a method which are provided with a passive equalizer improving the quality of a transmitted signal when a signal is transmitted/received to/from an external apparatus, and a system for the same. The present disclosure provides a signal transmission system for improving the quality of a transmitted signal. The signal transmission system may include a transmitter that transmits a signal; a receiver that receives the signal from the transmitter; a channel that is formed between the transmitter and the receiver and transmits the signal delivered by the transmitter; and a passive equalizer that is formed between the transmitter and the receiver and controls the signal so as to have a higher impedence than a predetermined impedance at a lower frequency than a predetermined frequency of the signal.
