Abstract: A circuit arrangement for a light signal receiver for receiving and recognizing light signals which are transmitted in a pulsed manner and to which ambient light of an undefinable intensity is parasitically superimposed. The circuit arrangement contains a two-pole light sensor and, for each terminal pole of the light sensor, a separate current-voltage converter for direct current is provided. The current-voltage converters have identical transmission behavior. Each terminal pole of the light sensor is connected to an identical signal input of a current-voltage converter. The current-voltage converters are connected as amplifying filters and are negative feedback-connected in terms of direct current and in a frequency-dependent manner so strongly via the input at which the terminal pole of the light sensor is located that the d.c. voltage at the terminal poles of the light sensor is constant independently from the intensity of the parasitic light.
