20080197919 - Fully differential demodulator with variable gain, and method for demodulating a signal: A demodulator includes input terminals, for receiving an input signal, and an amplifier stage having a gain. The input signal is amplitude-modulated and is defined by a carrier signal at a carrier frequency and by a modulating signal. The demodulator includes, moreover, a gain-control stage, coupled to the amplifier stage... Agent: Seed Intellectual Property Law Group PLLC

20080191799 - Arrangement for demodulating a vestigal sideband signal: An arrangement is described for demodulating a vestigial sideband signal component contained in an amplitude-modulated frequency signal, and preferably in a vision intermediate-frequency signal derived from a television signal. What distinguishes the invention is that there are provided two parallel, preferably identical, mixing stages (8a, 8b) that operate at a... Agent: Nxp, B.v. Nxp Intellectual Property Department

20080186088 - Procedure for bpsk demodulation corresponding to bpsk modulation with reduced envelope peaking: A system for and method of converting successive bits of digital data into BPSK symbols using one or more BPSK symbol constellations such that orthogonal BPSK constellations are referenced to successive bits of the digital data. The system and method may toggle between referencing first and second orthogonal constellations as... Agent: Conexant Systems, Inc
