    摘要: In order to transmit data supplied by a rotational speed sensor in the form of an alternating signal (ES) along with additional data (ZD) via a signal line (3), a sequence of electrical pulses (P) of a given duration is derived from the alternating signal. The intervals or interpulse periods of said sequence contain information on rotational speed. Additional data (ZD) is transmitted in the interpulse periods, wherein transmission of additional data (ZD; Bto to Bt7) is synchronized by the individual rotating signal sensor pulses (P). Preferably, the method is employed for active sensors (1), whereby the sensor pulses (P) and the additional data (ZD) are transmitted in the form of electric signals (Bto to Bt7). During standstill, when no sensor pulses (P) occur, transmission of additional data is triggered by auxiliary synchronization pulses (Sy2).

    摘要: A circuit arrangement is proposed for monitoring a control circuit which has a drive transistor (T1) with an inductive load (L) and a second transistor (T2) in a circuit arm parallel to the inductive load (L).
