This makes it possible to measure period signal spectrum exactly.
这一方法为周期信号频谱的准确测量提供了可能。
Because the outgoing signal is known, it is as easy to process as spread-spectrum signals.
正因为输出信号是已知的，所以它能更轻松地处理这样多频率的信号。
We can also further get marginal spectrum of the signal.
进而还可以得到信号的边际谱。
The probationary period plan estimates the signal power spectrum;
