20070120617 - Modulation apparatus and modulation method: A modulation apparatus which can be applied to the conventional analog PLL modulation system without using an enormous reference table, enables a phase distortion to be compensated accurately without requiring timing control with high accuracy, and can be applied to communication systems that do not perform amplitude modulation. In this... Agent: Stevens, Davis, Miller & Mosher, LLP

20070109066 - Method of continuously calibrating the gain for a multi-path angle modulator: A multiple path angle modulator includes a closed secondary loop added to a main control loop to automatically adjust a scaling factor related to high frequency gain. The main control loop is configured as a primary path to process the low frequency portion of the angle modulation signal, and the... Agent: Haverstock & Owens LLP

20070109067 - Phase lock loop rf modulator system: A phase lock loop RF modulator system including a phase lock loop circuit having a phase detector circuit responsive to an input reference signal and a feedback signal, an oscillator circuit responsive to the phase detector circuit for providing an output signal, a forward path from the phase detector circuit...
