一种抗干扰无惯性快速相敏解调器

An Anti-interference Non-inertia Fast Phase-sensibility Demodulator

为了较好地解决一般相敏解调器的交流分量大、响应速度慢的问题，提出了一种快速无惯性相敏解调器，其直流分量的大小正比于交流有用信号的幅值，而极性则取决于交流有用信号的相位。

In order to solve the problem that common phase-sensibility demodulator has large AC com- ponent and slow response velocity, an anti-interference non-inertia fast phase-sensibility demodulator is pre- sented. The DC component of this anti-interference, non-inertia, fast phase-sensibility demodulator is proportional to the amplitude of the useful AC signal, and its polarity is determined by the phase of the useful AC signal.
