20100074371 | Ultra narrow band frequency selectior for zero point modulated carrier - This invention claims a novel radio frequency receiver system for selecting a digitally modulated carrier frequency, and more specifically a Zero Point, amplitude Modulated (ZPM) carrier frequency. ZPM modulation does not create side-band frequencies, thus allowing individual carriers to be very closely spaced. Traditional methods of frequency selection utilize resonant tuning circuits in the antenna circuit and following amplifier circuits. Resonant tuning circuits are the assemblage of inductors and capacitors that are subject to parasitic oscillations, harmonic oscillations, as well as environmental effects. While modern technology has sufficiently overcome these detriments for traditional radio communication, ZPM theory desires to tune to a single frequency carrier with only one cycle of difference between carriers. Obvious to those skilled in the art, this requires a non-traditional method. For ZPM carriers, all signal-handling circuits must be non or insignificantly reactive and process the signal in linear fashion throughout the receiver signal path. This invention accomplishes the required functions by a unique combination of standard integrated circuits and circuit components. | 2010-03-25 |
