Title: George Nicholas Eberl: Innovator in AM Digital Broadcasting
Introduction
George Nicholas Eberl is a notable inventor based in Columbia, MD (US). He has made significant contributions to the field of digital broadcasting, particularly in AM in-band-on-channel (IBOC) technology. With a total of 3 patents to his name, Eberl's work has had a lasting impact on audio broadcasting.
Latest Patents
One of Eberl's latest patents is a method and apparatus for AM digital broadcasting. This innovative method utilizes a center channel signal in a central frequency band of an AM radio channel. The center channel signal is modulated by first and second versions of the program material to be transmitted. Additionally, sub-carriers in the upper and lower sidebands of the AM radio channel are modulated with digitally encoded portions of the program material. The upper sideband operates within a frequency band extending from about +5 kHz to about +10 kHz from the center frequency of the radio channel, while the lower sideband lies within a frequency band extending from about -5 kHz to about -10 kHz from the center frequency. The center channel signal, along with the upper and lower sideband sub-carriers, is transmitted to receivers. In a hybrid IBOC DAB version, the center channel signal includes a carrier that is analog modulated by the first version of the program material, with additional sub-carriers modulated by the second version. These additional sub-carriers are transmitted at a power spectral density level that is less than that of the analog modulated carrier. In an all-digital version, the center channel signal comprises two groups of sub-carriers modulated with the program material.
