    • 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.
    • 一种特别用于电视的信号传输系统,包括具有主信道和辅助信道的非线性预校正装置。 辅助信道包括具有两个放大信道的非线性乘积发生器,线性信道和非线性信道,其使得具有由其输出信号的差异提取的适当相位的非线性乘积。 主通道包括由并联的两个线性通道形成的电路,其输出信号在加法器中相加在一起。 添加辅助通道和主通道的输出信号。 该预制装置能够自动校正要设置的非线性产品。
