摘要: A Universal Serial Bus (USB) apparatus for USB communication is provided. The USB apparatus includes a Printed Circuit Board (PCB) including a circuit for communicating data with an external device according to a USB communication standard, a connector for connecting to a USB terminal of the external device, and a noise reduction circuit connected between an output terminal of the PCB and the connector for reducing noise of a data signal. The noise reduction circuit includes a common-mode filter for removing harmonic components generated between a ‘+’ data signal and a ‘−’ data signal and passing the ‘+’ data signal and the ‘−’ data signal, which operate in a differential mode.
