digital signal components and storing I and Q digital signal components in computer
memory and performing one or more of the claimed measurements.
The examiner turns to Tarantino for the disclosure of a calibration system which
discloses the claimed measurements on the magnitude and phase response and storing in a
memory, pointing to column 2, lines 59-65. Thus, the examiner holds it to have been
obvious to modify Thomas by specifically providing a distortion analyzer which measures
magnitude and phase responses, as disclosed by Tarantino, for the purpose of quickly and
accurately quantifying the frequency response of an instrument across its entire passband
without the use of additional equipment.
Finally, the examiner turns to Kroeger for a disclosure of “downconverting (40) said
relayed periodic RF signals to baseband in phase (I) and quadrature phase (Q) signal
components, converting (42) said I and Q signal components to I and Q digital signal
components and storing said I and Q digital signal components in a computer (44,64)”
[answer-page 4], pointing to column 7, lines 30-40. The examiner further identifies
column 8, lines 5-12, of Kroeger for a teaching of transmitting and receiving a wide- band
RF.
