摘要： A sample and hold phase detector for a phase locked loop includes a digital detector for detecting the frequency and phase difference between the reference signal and the voltage controlled oscillator (VCO) signal. In a first mode of operation, the digital detector generates a first signal relating the difference in frequency and in a second mode of operation generates a second signal relating the difference in phase. A capacitor stores the first or second signal depending on the operational mode of the digital detector. The capacitor is selectively discharged in response to a discharge signal produced by the digital detector when either the VCO frequency is higher than the reference frequency or following each detection of a phase difference. A first amplifier is used to bypass a portion of the loop filter to effect rapid changes in VCO frequency in the first mode while a second amplifier couples the control voltage to the VCO via the loop filter to maintain proper VCO frequency in the second mode.

摘要： In a frequency synthesizer phase locked loop including a reference oscillator, a variable reference divider (.div.M), a sample and hold phase detector, a loop filter, a voltage controlled oscillator and a variable divider (.div.N), a voltage converter for controlling the voltage of a control input to the voltage controlled oscillator is disclosed. In the preferred embodiment, the voltage converter has its input connected to the output of a first reference divider in the variable reference divider (.div.M) and its output connected to a control input (varactor diode) of the voltage controlled oscillator. The voltage converter clamps the divider reference signal from the first reference divider and provides a negative voltage level output to bias the varactor diode of the voltage controlled oscillator. Thus, the tuning range of the frequency synthesizer is increased.

摘要： A multiple conversion superheterodyne receiver system includes a first frequency synthesizer capable of generating any one of a number of predetermined first local oscillator frequencies for mixing with an incoming signal to produce a first intermediate frequency. A second frequency synthesizer selectively generates any one of two local oscillator frequencies corresponding to either high side or low side injection to be mixed with first intermediate frequency producing an appropriate second intermediate frequency. A frequency selecting circuit is operatively coupled to the first and second frequency synthesizer for selecting an appropriate one of the first local oscillator frequencies to tune the receiver to a desired channel and for selecting an appropriate one of the second local oscillator frequencies for avoiding receiver self-quieting spurious responses.

摘要： A method of programming a ROM for a multiple conversion frequency synthesizer provides a mechanism for avoiding receiver self-quieting. The method includes the steps of searching for frequencies which cause potential receiver self-quieting responses and selecting a second local oscillator frequency suitable for avoiding receiver self-quieting. A single bit of a ROM is used to represent possible second local oscillator frequencies synthesized by the frequency synthesizer which provide either high-side or low-side injection to the second mixer. Finally, the method includes the step of encoding the single second local oscillator frequency determining bit of the ROM appropriately for selecting the local oscillator frequency which avoids receiver self-quieting.

摘要： A non-invasive electrodynamic radiative electroporation system and method for safe in vivo delivery of specific radiant energy to physiologically inaccessible sites for selective destruction of biomolecular function of virions, particularly Covid-19 and its variants. The system and method applies a computer or like controller to generate, modulate, direct and deliver applied external electric fields from plural antennas to target tissues in the full respiratory tract, including lung microstructures, cardiovascular tissues and neuron networks. Electric fields exceeding a critical threshold-value interact with the virus lipid bilayer membranes, intra-membrane organelles, mRNA, and biomolecular scaffold assemblies, to destroy virion function through irreversible electroporation and electropermeabilization. Polarized electric fields are generated to provide force vectors in optimal dynamic angular distribution to the virion membrane surface and modulated within time-scales short compared to thermal transport characteristic times to effect the electroporation as an adiabatic process that preempts Joule heating of normal tissues.
