Abstract

A coil arrangement for a magnetic resonance system has a resonator that is followed by a modulator with which a magnetic resonance signal of the resonator is modulated onto a carrier frequency. An infeed element follows the modulator with which that magnetic resonance signal modulated onto the carrier frequency is supplied into a single transmission cable. In a corresponding reception circuit, an analog-to-digital converter is preceded by a demodulator with which the magnetic resonance signal is demodulated.
