  • Device and method to transform discrete voltage pulses to a phase-sensitive continuous signal
    Patent number: 10999109
    Abstract: Systems, methods, and apparatuses, for transform discrete voltage pulses to a continuous signal. One method may include receiving a pulsed-voltage signal. The method may also include alternately directing the pulsed-voltage signal between a pair of processing channels based on a modulation signal or another signal. The method may further include determining rate voltages corresponding to the pair of processing channels based on a pulse rate of the pulsed-voltage signal. Further, the method may include processing the rate voltages using low pass filters corresponding to the pair of processing channels to form filtered rate voltages. The method may also include determining a normalized differential output for the pair of processing channels based on the filtered rate voltages. The method may also include outputting the normalized differential output to an output connector.
