Abstract

본 발명은, 각 안테나에 의해 수신된 HF 신호를 각 안테나에 부속되어 있는 혼합단에서 수신기에서 발생된 제1발진기의 신호와 혼합하고 이에 의해 발생한 혼합신호를 제어 가능한 위상 상태와 부가하여 합산신호로 만드는, 다수 안테나를 구비한 특히 차량용 초단파 수신기에 관한 것이다. RDS 복조기로 부터 공급된 대체주파수가 저장된다. 혼합단들중 하나는 미리 주어진 수신 품질값에 미달할 때 수신기는 수신가치 있는 것으로 인지된 저장되어 있는 대체주파수로 절환한다.

Description

도면은 본 발명의 일실시예를 단순화하여 도시한 블록도이다.

Claims (3)

  1. 제1회로 상태에서는 각 안테나에 의해 수신된 HF 신호를 각 안테나에 부속되어 있는 혼합단에서 수신기에 발생된 제1발진기의 신호와 혼합하고 이에 의해 발생한 혼합신호를 제어 가능한 위상 상태와 부가하여 합산신호로 만드는, 다수의 안테나를 구비한 특히 차량용 초단파 수신기에 있어서, 상기 초단파 수신기는, 수신할 프로그램 신호와 동일한 프로그램 신호가 수신될 수 있는 대체 주파수들을 중간메모리내에 저장하는 RDS 복조기(18)(Radio-Data-System-Demodulator)를 구비한 회로 배치를 가지며, 상기 혼합단중 하나(4)를 짧은 시간 간격내에 제2회로 상태로 절환하여, 상기 혼합단(4)의 ZF 출력신호가 평가회로(16, 17, 18, 19)에 공급되고 그의 발진기 입력단이 절환된 제2혼합단(4)을 대체주파수들에 동조시키는 제2발진기(8)와 연결시켜 그 수신 품질을 평가하도록 하는 제어기(19)가 마련되어 있으며, 상기 제어기(19)는 제1회로 상태에서, 지금까지 수신되는 프로그램 신호가 미리 주어진 품질값에 미달할 때 상기 제1발진기(6)를 수신가치 있는 것으로 탐지된 대체주파수가 수신되도록 절환시키는 것을 특징으로 하는 초단파 수신기.
  2. 제1항에 있어서, 제2회로 상태에서, 프로그램신호의 재생중에, 상기 중간 메모리내에 저장된 대체주파수들에 탐지된 수신 품질 값이 부속되며, 그에 연결된 수신기는 다시 제1회로 상태로 전화되는 것을 특징으로 하는 초단파 수신기.
  3. 제1항 또는 제2항에 있어서, 상기 저장되어 있는 대체주파수의 값들을 현실화 하는 것은 미리 주어진 시간 간격으로 및/또는 미리 주어진 수신 품질 레벨이 미달될 때 이루어지는 것을 특징으로 하는 초단파 수신기.
