Abstract
Devices consisting of a signal source and a signal sink connected by a transmission channel for transmitting high-frequency signals, as well as digital signals between moving parts. By eliminating wave reflections, the signals are transmitted such that reliable wide-band transmissions are ensured.
Claims13
A system for transmitting and receiving high frequency signals between two parts, where a first part is a movable part and a second part is a stationary part, comprising:
- a signal source, located in the first part, for emitting a signal;
- a signal sink, located in the second part, for receiving the signal;
- a transmission channel, extending between the first part and the second part providing a signal current path for the signal and a defined return current path for a return current of the signal and for connecting the signal source and the signal sink, the signal current path and the defined return current path each comprising a first portion coupled with a second portion;
- and
- a coupler, provided in the transmission channel for coupling the first portion of the signal current path to the second portion of the signal current path;
- wherein the return current of the signal is returned from the second portion to the first portion along the defined return current path.

- a signal source, located in the first part, for emitting a signal;
- a signal sink, located in the second part, for receiving the signal;
- a transmission channel, extending from the first part to the second part providing a signal current path for the signal and connecting the signal source and the signal sink, the signal current path comprising a line that is terminated on at least one end by an impedance device and having a first portion and a second portion;
- and
- a coupler, provided in the transmission channel for coupling the signal from the first portion of the signal current path to the second portion of the signal current path;
- wherein the impedance device is matched to an impedance of the line to eliminate reflections.
