Empfängerschaltung zum Empfang von Zeitzeichensignalen

摘要

A resonance circuit (10) is formed by an inductive ariel (11) and at least one capacitor (12,13). AN integrated circuit (20) comprises an input amplifier (21), a filter stage (22), and following signal processing stages. Between the resonance circuit and the input amplifier of the integrated circuit is incorporated an extra filter stage (30) with a quartz (31) and a compensation capacitor (32). The resonance circuit is inductively a capacitively tapped, with the tap (17) coupled to a reference potential (16) such that two high points (14,15) are formed. On the input side the extra filter stage is coupled to the two high points, while on the output side it is coupled to the input amplifier signal input (211).
