Guest guest Posted July 14, 2008 Report Share Posted July 14, 2008 This is probably common knowledge to all of you electronic/EE types, but I do not recall it being mentioned in the past, may have missed something over the years. Anyway it might be important. While reading about pulsed FT-NMR they uses an RF pulse which is centered about frequency F. whose bandwidth is 1/t where t is the duration of the pulse. This means that these frequencies are produced simultaneously and all target nuclei in the sample will be excited. As long as they are able to be exicted near frequency F. In the case of the Gruner circuit at about 1300Hz gating if the center frequency produced is 1604KHz then it is really 1604 +- 1300 Hz. Of course if Rife used a faster gating rate or produced shorter duration pulses, then the bandwidth is much larger. For a 5uS pulse width the bandwidth is +- 200,000 cycles. The same of course would apply to the #4 if it indeed used gating. This allows for parts of the pathogen to pick out its own resonance frequency even if the center frequency is not exactly a resonance frequency. So by the use of impulse/gating the RF, Rife had a broadband transmitter Beamray Mike Quote Link to comment Share on other sites More sharing options...
