System for the quantitative measurement of impairments in the communication channel of a quadrature amplitude modulation data communication system
A system is provided for measuring communication channel impairments in a data transmitting system which employs quadrature amplitude modulation. The system rotates each point of sampled eye diagram information by a phase angle determined by the ideal value of the received point information so that...

| Zusammenfassung: | A system is provided for measuring communication channel impairments in a data transmitting system which employs quadrature amplitude modulation. The system rotates each point of sampled eye diagram information by a phase angle determined by the ideal value of the received point information so that the rotated point has its nominally maximum component on the real axis. |
