Modulators inventions 10/08

20080258831 - Amplifying apparatus: A pulse modulator generates a pulse-modulated signal by pulse-modulating and amplifying the amplitude component of an input signal. A low-pass filter filters the pulse-modulated signal from the pulse modulator, and generates an amplified amplitude signal which is obtained by amplifying the amplitude component. An error corrector generates a corrected amplitude... Agent: Sughrue Mion, PLLC

20080258832 - Digital phase modulator and corresponding method: A simple, interference-free digital phase modulator is to be provided. To this end, the phase modulator is provided with a counter for outputting a counter signal on the basis of a predetermined clock signal and a comparator, which receives a current counter state from the counter, in order to record...

20080258833 - Signal generator with directly-extractable dds signal source: A signal generator including a DDS-signal source that is configured to operate according to the principle of direct digital synthesis (DDS), and a PLL signal synthesizer that is configured to operate according to the principle of phase locked loop (PLL) using an output signal from the DDS-signal source as a... Agent: Ditthavong Mori & Steiner, P.C.

20080258834 - Pulse width modulation circuit: A pulse width modulation (PWM) circuit includes a turn on/off switch and a PWM controller. The first terminal of the turn on/off switch is coupled to a turn off voltage. The control terminal of the turn on/off switch receives a turn on/off signal to decide whether the circuit between the... Agent: J C Patents, Inc.

20080258835 - Circuit and method for glitch correction: Correction of glitches output from a delta-sigma modulator is accomplished using an integer boundary crossing detector and a FIR filter. The detector monitors a portion of an input to the modulator. The detector recognizes a transition from an all 1's bit pattern to an all 0's bit pattern or vice...

20080252392 - Discrete dithered frequency pulse width modulation: A system is described for generating a discrete noise-shaped variable switching frequency signal that may be used to define a digital pulse width modulation (“PWM”) period. The system may define a switching frequency waveform that may be used to generate a current switching frequency signal as a function of a... Agent: Brinks, Hofer, Gilson & Lione Freescale

20080246550 - Selective envelope modulation enabling reduced current consumption: A modulation system includes an amplitude modulation path and a phase modulation path coupled to the amplitude modulation path. One of the amplitude modulation path and the phase modulation path receive a reduced current such that the reduced current reduces power consumption by the system. Preferably, the amplitude modulation path... Agent: Haverstock & Owens LLP
