Title: The Innovations of Robert D Plowdrey
Introduction
Robert D Plowdrey is a notable inventor based in Livonia, MI (US), recognized for his contributions to the field of frequency modulation and signal processing. With a total of four patents to his name, Plowdrey has made significant advancements in technology that enhance the performance of audio and communication systems.
Latest Patents
Among his latest patents is the "Multipath detector using phase comparison of stereo pilot signal." This invention allows a frequency modulation (FM) stereo broadcast receiver to detect the onset of multipath interference by analyzing phase changes in the received stereo pilot signal. In this innovative design, the phase of the received pilot signal is compared to that of a regenerated pilot from a phase-locked loop within a stereo decoder circuit. The severity of a multipath event is determined by the phase shift detected at the onset of the interference.
Another significant patent is the "High speed frequency-shift keying decoder." This invention involves a frequency-shift keying (FSK) signal detector that splits an FSK signal into two paths. One path includes a phase-altering circuit with a variable frequency characteristic that provides either a phase lead or a phase lag, depending on the instantaneous frequency of the FSK signal. The phase-altered signal is then sampled in response to the signal in the second path to effectively decode a digital signal.
