Apparatus and Method for Generating a, Polar Representation of a Radio Frequency Signal Abstract of the Disclosure, An apparatus and method for generating a polar representation of a radio frequency (RF) signal (37). A RF receiver (18) receives the RF signal (37) having an amplitude component and a phase component. The RF signal (37) has a power level that varies over a wide dynamic range. The power level of the RF signal (37) is controlled responsive to a control signal (at line 40) to produce a gain controlled signal (at line 41). The amplitude of the gain controlled signal (at line 41) is determined to produce a first signal (at line 42) representative of the amplitude component of the …

Why it's free to use
- Filed June 28, 1994. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended June 28, 2014.
