Appeal No. 1999-2688
Application No. 08/751,057
1. An arrangement for graphically
displaying, in an IQ plane on a screen of a
display device, IQ values emitted at an output
of a demodulator for quadrature-amplitude-
modulated signals, comprising:
a data memory;
a processor, that controls the display
device, connected to the data memory;
a respective address of the data memory
allocated to each individual IQ value and a
respective pixel of the display device allocated
to each address of the data memory;
the processor directly connected to the IQ
output of the demodulator, the processor
determining an associated IQ value address in
the data memory for each IQ value.; and
a respective frequency stored under each
address of the data memory, the respective
frequency being a frequency with which a
respective address of the dates, and thereby the
corresponding IQ value, has been determined in a
predetermined acquisition time.
The examiner relies on the following reference:
Gray 5,479,606 Dec. 26,
1995
Additionally, the examiner relies on admitted prior art
[APA], ostensibly the admission, in the background section of
the instant specification, that it was known to display IQ
values emitted at the output of a demodulator for QAM signals.
