| Abstract: | The principles of realizing quadrature coherent detector by direct sampling of bandlimited signal are discussed in this paper. They have great practical value in engineering. Various proposed methods so far have been analysised and summarized. Their features and application condition are compared under the same index. They are also interpreted using the same point of view. |
