Abstract
Signal generator for the verification of color television receivers operating in a system in which the complex video signal comprises synchronization signals, a luminance signal Y and a subcarrier used for the transmission of two chrominance signals, which will be called A1 and A2, with each of the three signals R ', B' and V 'applied to the trichromatic reproduction device for respectively reproducing the optical components of the three primary colors, a linear combination of the Y signal of a at least of the two signals A1 and A2, said generator comprising means for elaborating various complex video signals intended to be applied to the video frequency stages of the verified receiver, characterized in that said generator comprises a device for processing at least one signal of complex video, in which for each image period the signals Y, A1 and A2 are null for a a remarkable surface region of the image supplied by the screen in the verified receiver when the corresponding full video signal is applied to it, while for another region of notable surface of said image the respective values of these three signals, two of which at less are not null, they are such that the corresponding nominal values of at least one of the three signals R ', B' and V 'are null.
