5) synchronous demodulation
同步解调
1.
The paper studied the principle of the all-angle MUM(Mass-Unbalanced Modulation) reading realized through synchronous demodulation,discussed the factors that influenced the reading precision,and analyzed the reading errors resulted from the non-orthogonality of the electrodes-fixed frame and the inconsistent between the scale factors of different measuring channels.

2.
MFSK signal can be demodulated by synchronous demodulation and envelope demodulation.
MFSK信号可用同步解调和包络解调两种方式进行,采用不同解调方式的MFSK通信系统具有不同的性能特点,重点讨论采用同步解调的MFSK通信系统的抗噪声性能。
3.
In synchronous demodulation, frequency and phase of a local carrier must be synchronous with sending station, distortion will be caused in output signals of demodulation as frequency error and phase error occur in the local carrier.
在同步解调中,本地载波的频率和相位必须与发送端载波同步,当本地载波存在频率或相位误差时,会使解调输出信号产生失真。
6) synchronized modulation
同步调制
1.
The design scheme is tested and debugged on a three-phase asynchronous motor in the end,and the results show that the method of mixed modulation has lower current harmonic,more efficient use of supply voltage,lower noise than the synchronized modulation and asynchronized modulation.
分别用同步调制、异步调制、混合调制三种方法实现电压空间矢量脉宽调制型逆变器,在一台三相异步电动机上进行了试验调试,实验结果表明:与同步和异步调制相比,混合调制时电机电流的谐波小,电压利用率高,电机的高频噪声低。
