Low-power modulation. In an AM transmitter modulation of an RF stage prior to the final high-power stage. This system has the advantage that the modulator need only be of low power but the stage following the modulated amplifier must be linear to avoid distortion of the modulation envelope. 3, record 1, English, - low%2Dpower%20modulation

Roll Erection. During the first phase of vertical alignment, the platform roll gimbal is case aligned and erects to the error signal from roll CX... The roll error signal is applied to [an] amplifier. After amplification, it is demodulated..., properly phased and limited by network... and then combined with a feedback voltage from [the] roll tachometer..., which provides damping action. The resultant signal is modulated, amplified and fed to the platform roll gimbal power amplifiers... 1, record 3, English, - damping%20action
