The invention relates to a transmitting/receiving device (12) for a bus system (1) and to a method for reducing line-conducted emissions. The transmitting/receiving device (12) has a transmitting stage for transmitting a transmission signal (TxD) to a first bus wire (41) of a bus (40) of the bus system (1), wherein an exclusive collision-free access of a subscriber station (10, 20, 30) to the bus(40) of the bus system (1) is ensured at least temporarily in the bus system (1), and for transmitting the transmission signal (TxD) to a second bus wire (42) of the bus (40), a receiving stage (120)for receiving the bus signal (CAN_H, CAN_L) transmitted on the bus wires (41, 42), and an emission-reducing unit (15) for controlling a switch-on path of a first stand-off device (1252) in the transmitting stage depending on whether or not a dominant state (111) of the transmission signal (TxD) occurs. 提供了一种用于总线系统（1）的发送/接收装置（12）和一种用于减小有线发射的方法。该发送/接收装置（12）具有：发送级，该发送级用于将发送信号（TxD）发送给该总线系统（1）的总线（40）的第一总线芯线（41），在该总线系统（1）中，至少有时确
