| 摘要 |
The invention relates to a device (100) for detecting analog signals, in particular for detecting surroundings, said device having a control and signal analyzing unit (101) and at least one sensor (102) with a signal receiving unit (104) for detecting received signals and an amplifier (105) for amplifying the received signals. The sensor (102) is connected to the control and signal analyzing unit (101) via one or more transmission lines (103, 106, 107). The amplification of the amplifier (105) can be modified, and the device is designed to transmit the received signals amplified by means of the amplifier (105) via the same transmission line (103) via which information for adjusting the amplification and/or the supply voltage of the sensor (102) is also transmitted simultaneously. The invention further relates to a method for operating the device (100) according to the invention and to a mobility aid which has the device according to the invention. |
