A supply voltage is needed in conventional electronic circuits used for processing signals, such as counting pulses. The supply voltage supplies the logic circuit components. Especially apparatuses which have to be operated over a longer period of time or/and in remote sites of use and are dependent upon a supply voltage are impaired with the dependency-related disadvantages, such as the necessity of expensive EEPROMs or significantly increased maintenance expenditure. The present invention relates to an electronic circuit which is provided with an input (5) for inputting at least one information signal, an energy means (2) for converting the energy that is present in the at least one information signal into a supply voltage, a control means (3) for generating at least one switch-on control signal when the information signal is input and a signal processing means (4) for storing information which is represented by the at least one information signal and/or for evaluating information which is represented by the at least one information signal and for storing the secondary information which is obtained by the evaluation. At least one ferroelectric flipflop (26) is used. The signal processing means (4) can be activated by the at least one switch-on control signal for evaluating and/or storing purposes. The at least one information signal can be or is the only energy source for the electronic circuit (1) during the evaluation and/or storing process.
