Latest Patents

Barry F Koch holds a patent for a "Diversity receiver for FM stereo utilizing a pilot tone multiple." This invention focuses on an FM stereo receiving system and a method for aligning phases of RF signals received by multiple antennas. The system includes two antennas that receive RF signals at a common frequency but potentially different phases. It features an FM receiver with a detector output and a pilot output, where a pilot tone, such as a 19 kHz pilot tone, is present. The system also incorporates a summer to sum the RF signals and provide the summed signal to the receiver. An amplitude modulator is positioned between one of the antennas and the summer to modulate the antenna's RF signal at a perturbation frequency, which is a whole number multiple greater than 1 of the pilot tone. This innovative design allows the receiver to produce a phase signal that helps align the phases of the RF signals.
