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.
