Time the beam right and the star could be turned, in effect, into an FM transmitter-broadcasting to the universe on the underlying carrier-wave of the Cepheid's pulsation.
By digital simulation, the Ac carried wave system and its equivalent Dc system are checked and the feasibility of Dc method equivalent to the Ac carrierwave system is verified.
通过数字仿真，比较了交流载波系统和其等效直流系统，验证了交流载波系统等效直流方法的可行性。
