Method and arrangement for forming reception pulses in an infrared receiver

A method for forming an output reception pulse in a receiver wherein an input signal from an upstream comparator that recognizes light pulses is newly formed and output as the output reception pulse for evaluation by means of a downstream arrangement, wherein:

• in a first step, the input signal is delivered by the upstream comparator;
• the input signal is delayed by a delay arrangement;
• generation of a time reference by a time reference generation arrangement controlled by the input signal is started;
• controlled by the input signal delayed in the first step, forming of an output reception pulse by an output pulse production arrangement is started;
• upon completion of the generation of the time reference, an examination of a level of the input signal is conducted which carries out a back-reference to duration of the output reception pulse;
• and subject to results of the examination, the duration of the output reception pulse is adjusted by the output pulse production arrangement, wherein duration of the output reception pulse is independent of actual pulse duration of the input signal delivered by the upstream comparator;
• and
• wherein the forming of the output pulse by the output pulse production arrangement is done such that forming of a first pulse and a second pulse is started in parallel and subject to the examination of the input signal level either the first or the second pulse is emitted at the output.

An arrangement for forming an output reception pulse in a receiver wherein an input comparator signal from an upstream comparator that recognizes light pulses is newly formed for evaluation by a downstream arrangement, wherein an input of a delay arrangement is connected to an output of the upstream comparator, for supply of the input comparator signal, wherein a first output of the delay arrangement is connected to a first input of a downstream output pulse producing arrangement and a second output of the delay arrangement is connected to a time reference generating arrangement, the first output and the second output being different outputs of the delay arrangement, wherein an output of the time reference generating arrangement is connected to a second input of the output pulse producing arrangement and, wherein an output of the output pulse producing arrangement is connected to the output OUT of the arrangement for forming the output reception pulse, wherein duration of the output reception pulse is adjusted by the output pulse producing arrangement, and duration of the output reception pulse is independent of actual pulse duration of the input comparator signal;

• and
• wherein the delay arrangement is comprised of a series connection of a first and a second delay arrangement parts and an arrangement for pulse reconstruction installed between the first and second delay arrangements parts.
