Title: 通信線上の制御された形状の被切換信号のための送信機
IPC: H03K4/92

Abstract: 通信線（１）上の制御された形状の被切換信号のための送信機（４）は、該通信線に印加されるべき被切換信号を生成するキャパシタ（１９）を含む信号発生器を備える。キャパシタは、被切換信号の縁部を定義するように入力信号（ＴＸ）に応答して充電電流（Ｉ Ｃ ）により充電される。充電手段（２４，２５）は、キャパシタ電圧（Ｖ Ｏ ）に応答して、キャパシタ電圧のプログレッシブ関数である連続的大きさを有するフィードバック電流（Ｉ Ｅ ）を発生するフィードバック・ループを備える。充電電流（Ｉ Ｃ ）は、フィードバック電流（Ｉ Ｅ ）の関数である。抵抗（Ｒ；Ｒ １ ，Ｒ ２ ）は、キャパシタと共に、フィードバック電流の時定数を制御するのを可能にするＲＣ回路を形成する。フィードバック・ループは、第１及び第２のフィードバック電圧（Ｖ Ｈ ，Ｖ Ｌ ）の一方がキャパシタ電圧（Ｖ Ｏ ）の上昇関数であり、その他方がキャパシタ電圧（Ｖ Ｏ ）の下降関数である第１及び第２のフィードバック電圧（Ｖ Ｈ ，Ｖ Ｌ ）を発生するのが好ましい。フィードバック電流（Ｉ Ｅ ）は、最初に、フィードバック電圧（Ｖ Ｈ ，Ｖ Ｌ ）のうちの一方の関数として発生し、次いでフィードバック電圧のうちの他方の関数として発生され、それによりフィードバック電流（Ｉ Ｅ ）の変化率は、フィードバック電圧の一方が選択される間時間と共に増大し、且つフィードバック電圧の他方が選択される間時間と共に低減する。フィードバック電流（Ｉ Ｅ ）の変化率は、キャパシタ電圧が被切換信号の縁部の少なくとも一部分（４０，４２，４４，４６）の間時間の指数関数として実質的に変化するようにキャパシタ電圧（Ｖ Ｏ ）の関数であり、且つ殆ど高調波を持たない正弦波の半サイクルに密接に近似されるように、別の部分（４１，４３，４５）の間時間の線形関数であり得る。
