Patent number: 7714631Abstract: There are provided, in a clock generator for generating a plurality of output clock signals, an apparatus and method for synchronizing the clock generator to an input reference clock in the presence of a jittery input clock provided to the clock generator from a PLL. The clock generator and the PLL each have a divider with the same ratio. The apparatus includes a synchronizer (205) and a state machine (210). The synchronizer receives the input reference clock and the jittery input clock, and generates there from a synchronized input clock signal with respect to the jittery input clock. The state machine receives the synchronized input clock signal and the jittery input clock, synchronizes with the synchronized input clock signal using the jittery input clock, and abstains from a re-synchronizing operation when the jittery input clock has a jitter of up to a pre-defined maximum number of clock widths.Type: GrantFiled: May 5, 2005Date of Patent: May 11, 2010Assignee: Thomson LicensingInventor: Gabriel Alfred Edde

Patent number: 7567298Abstract: A television set includes an ATSC (Advanced Television Systems Committee) receiver, which includes an NTSC (National Television Systems Committee) co-channel interference detector based on carrier tracking of the NTSC video carrier signal. The NTSC co-channel interference detector includes a carrier tracking loop and a decision device. The carrier tracking loop processes a received signal for detecting the possible presence of the NTSC video carrier signal and for providing a tracking signal representative thereof. The decision device receives the tracking signal and recovers a DC offset therefrom. The decision device then determines that NTSC co-channel interference is present if the DC offset signal is greater than a predefined threshold.Type: GrantFiled: November 12, 2003Date of Patent: July 28, 2009Assignee: Thomson LicensingInventors: Ivonete Markman, Gabriel Alfred Edde

Patent number: 7038730Abstract: A communications receiver receives a signal which has not been filtered by a matched pulse shaping filter. In the receiver, a circuit element processes the received signal and as a part of that process introduces additional linear distortion into the processed received signal. A matched filter, coupled to the circuit element, generates a fully matched filtered signal compensated for the distortion intrinsic to the received signal pulse shape and the distortion introduced by the circuit element.Type: GrantFiled: July 10, 2002Date of Patent: May 2, 2006Assignee: Thomson LicensingInventors: Ivonete Markman, Gabriel Alfred Edde
