摘要

a sendersuchlaufverfahren for receivers electronics consists of three suchlaufabschnitten per scan: a quick scan, a gegenlauf and a slow, progressive scan. the scan by means of a guided abstimmspannungsgeneratorschaltung (2).a during the rapid suchlaufes when running through a abstimmlage a tuner (1) to its signalausgang (18) produced senderanzeigesignal (s (a) is a steueranordnung (17) fast scan still and turn a fast scan entgegengerichteten slow signing on on the suchlaufspannung delaying by a predetermined amount.after the steueranordnung slow scan on and, at the same time, the signalausgang (18) of the tuner (1) on the stopeingang (20) of a stopschaltung (21) possible.this technique enables a high suchlaufgeschwindigkeit for quick scan that going through the vote on a transmitter is recognized, the abstimmanordnung but only after the defection of the received transmitter from the rapid scan stopped.
