A digitizer for digitizing a magnetic resonance (MR) signal is hereby disclosed, the digitizer comprising at least two analog amplifiers (102<SUB>1</SUB>, 102<SUB>2</SUB>... 102<SUB>n</SUB>) electrically connected in parallel and configured to amplify the MR signal, wherein each analog amplifier has a different analog gain value, a measuring unit configured to measure a characteristic of the MR signal, a sample selection module (108) configured to generate a selection signal (SS) based on the measured characteristic, and a first analog-to-digital converter (104) configured to digitize the amplified MR signal from one of the at least two analog amplifiers, based on the selection signal. |
