PROBLEM TO BE SOLVED: To make graphic display of IQ values, which is emitted from a demodulator for orthogonal amplitude modulation signals, in the IQ area on a screen. SOLUTION: Individual IQ values are allocated to addresses in a data memory 9, and pixels of a display device 7 are allocated to different addresses of the data memory 9. Different pieces of information given to the IQ values, for example the specified pixel retention times, are accommodated in the addresses of the data memory 9. A processor 5 is connected directly with the IQ output of a demodulator 2, and the relevant IQ value address is decided in the data memory 9 for each IQ value. |
