求翻译：只要把测量信号乘上对应同频率零相位的正弦波和零相位的余弦波，积分后就可直接分离出实部信号DR和虚部信号DX。是什么意思？

As long as the measurement signal multiplied by the corresponding zero-phase sine wave with frequency and zero phase cosine wave, points can be directly isolated after the real and imaginary parts of the signal DR signal DX.

As long as the measurement signal multiplied by the corresponding with zero-phase sine wave frequency and zero-phase the cosine wave, points can be directly after separation and virtual DR signals a real Ministry Department DX signals.

So long as rides the survey signal corresponds the same frequency zero phase the sine wave and the zero phase cosine wave, after the integral may separate real part signal DR and imaginary component signal DX directly.

As long as the frequency measurement signals and multiply its zero-phase sine and cosine of zero-phase, the credits before you can direct separation of signal DR real part and imaginary part signal DX.

So long as multiply with measuring the signal and correspond to it with the sinusoidal wave of a phase place of frequency and cosine wave of a phase place, can isolate real department signal DR and empty department signal DX directly after the total mark.
