Abstract: A power amplification device for high-frequency amplitude-modulated signals comprises a first and a second amplifier employed respectively for amplification of a reduced-level HF modulated carrier signal and for amplification of the simple HF carrier signal extracted from the HF standard modulated signal and supplies in parallel the amplifier and a subtracter device through which the first amplifier receives the HF standard modulated signal. This results in excellent performances, high efficiency and stability, ease of maintenance and reliability.

Abstract: The transmission system essentially involves separate amplification followed by a combination under predetermined conditions of relative amplitude and phase, of a carrier signal modulated by the video-frequency information and having a reduced carrier level with the same unmodulated carrier, thus permitting a considerable improvement in both efficiency and reliability of conventional transmitters.

Abstract: A signal transmission system, particularly for television, comprising a nonlinearity precorrection device having a principal channel and a subsidiary channel. The subsidiary channel comprises a nonlinearity product generator with two amplification channels, a linear channel and a nonlinear channel which enable nonlinearity products having a suitable phase to be extracted by the difference of their output signals. The principal channel comprises a circuit formed from two linear channels in parallel whose output signals are added together in an adder. The output signals of the subsidiary channel and the principal channel are added. This precorrection device enables automatic correction of the nonlinearity products to be set up.
