Claims (7)
- 信号を所定の品質のものであり、詳細には正当なFM局から来ていると識別する基準を満たすFM信号が受信されるまで受信周波数帯域を走査することによってラジオFM受信機を自動同調させる方法であって、少なくとも同調の間、恒久的に、前記FM信号が前記基準を満たすか否かが確かめられ、その後、その結果が所定の回数読み出され、前記回数の少なくともほとんどにおいて前記基準が満たされる場合にしか前記FM信号が記憶されないことを特徴とする方法。
- 前記結果が10回読み出され、10回のうち少なくとも8回前記基準が満たされる場合にしか前記FM信号が記憶されないことを特徴とする請求項1に記載の方法。
- ラジオFM受信機において受信されるFM信号が、該信号を所定の品質のものであり、詳細には正当なFM局から来ていると識別する基準を満たすか否かを記録するための手段と、前記FM信号が前記基準を満たすか否かが記録される所定の回数の合間に前記FM信号が前記基準を満たす回数を記録するための計数手段とを備える自動同調装置。
- 請求項3に記載の自動同調装置を有する請求項1又は2の方法を達成するためのラジオFM受信機。
- 請求項1又は2の方法に基づいて自動同調装置においてFM信号を処理するためのアルゴリズム。
- 請求項3に記載の自動同調装置を有するラジオFM受信機と協働する又はラジオFM受信機内の信号処理手段において走らせることが可能なコンピュータプログラム。
- 信号処理手段によって実行されるよう命令を運ぶ情報担体であり、前記命令が、前記処理手段が請求項1又は2に記載の方法を行なうことを可能にするような命令である情報担体。
