Abstract
A method for discriminating between externally-radiated, electromagnetic interference signals and electromedical scanning signals comprises the following steps: the preamplification of the scanning signals by means of two preamplifiers; the comparison of the preamplified scanning signals by a comparator; the phase-sensitive evaluation of the comparator output signal for differentiating between scanning signals and interference signals; the feedback of the comparator output signal to the amplification control of the preamplifiers such that the comparator output signal is minimized when an interference signal is detected.
