DEVICE FOR THE MEASUREMENT IN OPERATION OF NON- LINEARITY PRODUCTS IN A TELEVISION TRANSMITTER

摘要

DEVICE FOR THE MEASUREMENT IN OPERATION OF NON-LINEARITY PRODUCTS IN A TELEVISION TRANSMITTER The present invention relates to a device for measuring in operation the non-linearity of equipment for the transmission of composite television signals. It comprises a processing circuit which samples an intermodulation product located outside the useful spectrum transmitted, but within the band of the equipment generating it, whose measurement is validated by a control circuit for predetermined instantaneous or average values of the vision carrier.
