ABSTRACT:
In a method and arrangement for forming reception pulses, output signals of an upstream comparator which recognizes light pulses are used to evaluate a downstream arrangement and are newly formed and emitted as pulses. The aim is to produce a method and an associated circuit arrangement for forming reception pulses which represent a saving in energy, whereby said arrangement can be integrated into existing receiver systems, requires no external time base and can work with the signal of an upstream comparator. In a first step, an input signal delivered by an upstream comparator is delayed, whereupon a time reference is produced in a controlled manner and an output pulse begins to be formed in a controlled manner by means of the delayed input signal from the first step. The input signal level is examined once production of the time reference is completed. The examination refers back to the length of the received pulse, and the duration of the output impulse is adjusted according to the results of the examination.
