Abstract
A device is proposed for monitoring the function of electronic equipment, in particular equipment controlled by microprocessors. In such devices, the regular occurrence of control pulses is monitored in that a capacitor which can be charged or discharged in accordance with the control pulses is connected to a threshold stage, which in the case of a persistent absence of control pulses generates a signal having a reset phase of predetermined duration and an active phase also of predetermined duration for the equipment in a periodic sequence. The durations, of the reset phase and the active phase are freely selectable independently of one another, the duration of the active phase preferably being substantially shorter than that of the reset phase.
