Claims (8)
- 同期化信号(S)を受信するためのデータ伝送装置(E)と、データ伝送装置(E)をクロックするための発振器装置(O)とを有する聴音装置において、発振器装置(O)はフリーホイーリング発振器を含み、データ伝送装置(E)に相関装置(K)が接続され、その結果、あらかじめ与えられ得る基準信号が相関装置(K)により同期化信号(S)と相関され、相関結果に基づいてフリーホイーリング発振器が微調整されるようになっていることを特徴とする聴音装置。
- フリーホイーリング発振器に発振器の微調整のために切換可能な容量が接続されていることを特徴とする請求項1記載の聴音装置。
- ディジタル式に形成され、同期化信号(S)が周期的に繰り返されるバーストからなることを特徴とする請求項1又は2記載の聴音装置。
- フリーホイーリング発振器が各バーストによって微調整されることを特徴とする請求項3記載の聴音装置。
- バーストがバーカーコードに従ってコード化されていることを特徴とする請求項3又は4記載の聴音装置。
- アナログ式に形成され、同期化信号(S)が周期的に繰り返されるチャープからなることを特徴とする請求項1〜5のいずれか1つに記載の聴音装置。
- 発振器装置が、2つの同期化信号(S)間のカウント信号を生ずるためのカウントユニットと、周波数特性を記憶するための記憶ユニットとを有し、その結果カウント信号からフリーホイーリング発振器が合わされるべき直接又は間接の周波数が決定されることを特徴とする請求項1〜6のいずれか1つに記載の聴音装置。
- 記憶ユニットにルックアップ・テーブルが記憶され、ルックアップ・テーブルからカウント信号を介して容量の接続及び切離しが間接的な周波数尺度として決定されることを特徴とする請求項7記載の聴音装置。
