The invention relates to a method for transmitting analog and digital information while transmitting energy between a power transmitter () and a power receiver () which is galvanically isolated from the power transmitter, having the following steps: a) providing the analog () and digital () information to be transmitted; b) defining the number nof possible values AD, i=1 to nwhich are possible when digitizing the analog information and defining the value range of the values AD; c) assigning a digital value D(in binary notation) to the digital information; d) defining a minimum number of events nto be transmitted; e) determining a maximum number of events nto be transmitted; f) defining a first set of values ndefined by: n(AD)=n+f1(AD), i=1 to n; g) defining a second set of values ndefined by: n(ADi)=n&#x2212;f2(AD), i=1 to n; h) digitizing the analog information in order to obtain a digital analog value AD; i) determining a number of events n(ADx)=n+f1(AD) for the respective digital value Dbit to be transmitted if the current digital value Dbit to be transmitted is a 0; and defining a number of events n(AD)=n&#x2212;f2(AD) for the respective digital value Dbit to be transmitted if the current digital value Dbit to be transmitted is a 1 or vice versa; and j) transmitting a signal which correlates at least to the number of events determined in step i). The invention further relates to a corresponding device for carrying out the method.
