摘要：It is an object of the present invention to provide a DSB-SC system capable ofsuppressing a third order component. The DSB-SC modulation having high extinction ratiocan be realized by adjusting the first order component, which is generated by applying amodulation signal (3f), and the third order component, which is generated by applying abasic signal (f), to have reversed phase and the same intensity level, and then by applyingthe first order component to the third order component, these two components canceleach other.
