Abstract
In an arrangement for graphic display, in the IQ plane on the screen of a display device, of IQ values emitted at an output of a demodulator for quadrature-amplitude-modulated signals, an address of the data memory is allocated to each individual IQ value and a pixel of the display device is allocated to each address of the data memory. Information allocated to the respective IQ value, e.g. a predetermined pixel hold time, is stored under each address of this data memory. A processor is directly connected to the IQ output of the demodulator, and determines the associated IQ value address in the data memory for each IQ value.
