Claim 10:
11. A method for wireless transfer of a clock signal and a control signal with a magnetic resonance tomography unit, the method comprising:
modulating an electromagnetic data signal at a first modulation frequency and transmitting a first modulated electromagnetic data signal with a transmitter;
receiving the electromagnetic data signal with a first sensor;
filtering a first output signal from the first sensor with a filter;
modulating the electromagnetic data signal at a second modulation frequency and emitting a second modulated electromagnetic data signal with the transmitter;
receiving an optical signal with the first sensor;
filtering a third output signal from the first sensor with the filter;
stabilizing a clock frequency of an oscillator with the first output signal and the third output signal from the first sensor; and
demodulating a control signal from the first output signal and the third output signal by an amplitude demodulator;
wherein a frequency of the clock signal is an odd multiple of the first modulation frequency and the second modulation frequency.
