Title: Jeffry Joseph Miller: Innovator in Signal Processing
Introduction
Jeffry Joseph Miller is a notable inventor based in Warminster, PA (US). He has made significant contributions to the field of signal processing, holding a total of 2 patents. His work focuses on developing advanced techniques for interference cancellation and adaptive filtering.
Latest Patents
Miller's latest patents include an innovative interference canceller. This device features an input that receives a composite signal, a reference circuit, and a cancellation circuit. The interference canceller derives its own reference signal by suppressing the desired signal within a sampled quantum of the composite signal. The resultant reference signal closely resembles the interference signal, containing primarily the interference itself. This internally produced reference signal is continuously adjusted in amplitude and phase, allowing for effective summation with the composite signal in the cancellation circuit. The output effectively contains the desired signal with significantly suppressed interference.
Another of Miller's recent inventions is an adaptive filter designed for frequency modulation. This filter utilizes an audio tone multiplexed into the baseband modulation spectrum as a pilot tone. This pilot tone controls the adaptation of the filter's effective and variable bandwidth, optimizing selectivity and rejection of both wideband and narrowband interference. The filter continuously adjusts its bandwidth based on the signal-to-noise ratio of the detected tone, ensuring minimal distortion while accommodating actual signal bandwidth. Additionally, it compensates for transmitter drift of the center frequency, making it applicable at radio or intermediate frequencies.
