Title:
高次成分を消去可能な光振幅変調システム
Document Type and Number:
Japanese Patent JP4552032
Kind Code:
B2
Abstract:
It is an object of the present invention to provide a DSB-SC system capable of suppressing a third order component. The DSB-SC modulation having high extinction ratio can be realized by adjusting the first order component, which is generated by applying a modulation signal (3f m ), and the third order component, which is generated by applying a basic signal (f m ), to have reversed phase and the same intensity level, and then by applying the first order component to the third order component, these two components cancel each other.
