Claims (3)

  1. 유선전송로의 전송가능한 주파수 대역내의 전역 또는 일부대역내에 있어서 밸런스 상태로 되는 브리지 회로로 구성하여 동일의 주파수 또는 근접한 주파수를 사용하여 쌍방향 동시통신을 가능하게 한 것을 특징으로 하는 취소회로.
  2. 제1항에 있어서, 브리지 회로는, 주파수 특성 보정회로 및 이상회로(phase sift)구비하고, 전송로의 임피이던스변화에 의한 영향과, 자신이 구성하는 소자자체에 의해 일어나는 언밸런스상태를 보정하고, 상대적인 밸런스 상태를 얻는 것을 특징으로 하는 취소회로.
  3. 전송로를 사이에 둔 단말기기의 쌍방에 취소회로를 구비하고, 상기 취소회로는 전송가능한 주파수 대역내의 전역 또는 일부대역내에 있어서 밸런스상태로 하기 위한 브리지 회로로 구성하는 것이고, 동일주파수 또는 근접한 주파수에 있어서 쌍방향 동시통신을 가능하게 한것을 특징으로 하는 전송방식.
