analog modulation techniques are: Amplitude modulation (AM) (here the amplitude of the carrier signal is varied in accordance to the instan eous amplitude of the modulating signal) Double-sideband modulation (DSB) Double-sideband modulati

包含飞行器飞行中的姿态控制，如侧滑角，倾斜角，滚转角，俯仰角，构成不同频率的调制信号，包括单边带、双边带、载波抑制及四倍频。- It comprises aircraft flight attitude control, such as slip angle, tilt angle, roll angle, pitch angle, Constituting the modulated signals of different frequencies, Including single side

独立成分分析算法降低原始数据噪声，包括单边带、双边带、载波抑制及四倍频,有借鉴意义哦。- Independent component analysis algorithm reduces the raw data noise, Including single sideband, double sideband, suppressed carrier and quadruple, There are reference Oh.
