ABSTRACT:
A device for the automatic precorrection of non-linearities of a power amplification chain in a common channel television transmitter. The device has a first circuit for detecting the component to be corrected prior to amplification and addition of the components to be simultaneously amplified, a circuit for selecting the same components after amplification in a common channel, an attenuator of the latter component having an attenuation coefficient equal to the linear part of the amplification chain gain, a second detection circuit, an analog divider receiving the two detected components, whereof the output is coupled to the precorrection control input of a precorrection circuit upstream of the first precorrection circuit.
