digital communication device for receiving units, digital communication devices and digital communication system

摘要

Topic As forms communication interface with only the passive device, devising, cheaply, at the same time, it is low, the reception unit for the communication device which is driven by electric power consumption is offered.SolutionsThe 2nd diode group 340 which is in series connected to opposite direction the 1st diode group vis-a-vis 330 which is in series connected to forward direction the input edge vis-a-vis 310 being connected to network 10 and the input edge 310 and the input edge 310 and, in the input buffer the output edge 370 which is connected 360 which is provided on the connection line of the point between diode 341,342 where 1st diode group 330 is formed and the point between diode 341,342 where 2nd diode group 340 is formed and input buffer 360 and, it has.
