发明名称 CIRCUIT FOR MANIPULATION-PROTECTED RECEPTION OF AN OOK-MODULATED SIGNAL
摘要 The invention relates to a circuit for receiving an OOK-modulated signal, in particular for use in a data carrier of an identification system. The inventive circuit has a demodulator circuit (demod), a downstream decoding circuit (decod), and a sequential control (SM) for controlling in particular the reception, demodulation and processing of the received data. Between the demodulator circuit (demod) and the decoding circuit (decod), a switching element is fitted which can be controlled by the sequential control (SM). The input of the switching element is connected to the output of the demodulator circuit (demod); the first output of the switching element is connected to the input of the decoding circuit (decod). The switching element (S) has a second output which is connected to the reset input of the circuit.
