    Abstract: A transmitting device and a method for transmitting two high frequency signals for a magnetic resonance tomograph are provided. The transmitting device includes a shielded balanced transmission line, a first signal driver, and a second signal driver. The first signal driver and the second signal driver feed the first high frequency signal to a first conductor and the second high frequency signal to a second conductor of the balanced transmission line. A shielding of the balanced transmission line has an electrical connection to a common ground potential for the first signal driver and the second signal driver.

    Abstract: An arrangement for the transmission of magnetic resonance signals that are received with the aid of local coils is provided. The magnetic resonance signal is fed to an analog/digital converter and digitized by the analog/digital converter. The magnetic resonance signal is compressed in amplitude before being fed to the analog/digital converter, is low-pass filtered or band-pass filtered, and is expanded after digitization by the analog/digital converter. A clock rate that is higher by a factor 2n than a sampling rate n of the analog/digital converter (ADC) is used for the digital expander. A digital equalizing filter for compensating for a filter transmission function in a transition range may also be used.

    Abstract: A method for generating motion information for an at least partially moving examination region includes outputting at least one first excitation signal with a first frequency band. The first excitation signal is picked up with a receive coil arrangement of a magnetic resonance system. The at least one coil of the receive coil arrangement is configured to pick up a receive frequency band that includes the first frequency band. At least one item of motion information for the examination region is determined from the picked up first excitation signal.

    Abstract: A communication method for communication between a first and a second communication apparatus, where at least one wanted signal is transmitted from the second communication apparatus to the first communication apparatus is provided. The method includes sending a first carrier signal at a first frequency using the first communication apparatus. The method also includes receiving the first carrier signal using the second communication apparatus and generating a second carrier signal at a second frequency. The method includes changing the second frequency and/or a specified phase angle, and/or modulating the second carrier signal in each case as a function of the wanted signal in order to generate a transmit signal. The transmit signal is sent by the second communication apparatus, and the transmit signal is received and demodulated in order to recover the wanted signal using the first communication apparatus.
