Abstract

In this arrangement, three digital colour signals and a digital intensity signal are each supplied to one inverting switchable limiter amplifier and the outputs of the limiter amplifiers provided for the digital colour signals and the output of the limiter amplifier provided for the digital intensity signal are connected to resistance matrices, colour signals with the aid of which the analog value suitable for the colour monitor are derived.
