Filed:

Dec 31, 2009

Appl. No.:

12/650699

Inventors:

Daniel Harley Wagner - Grayslake IL, US
Michael Frederick David Olley - Lake Zurich IL, US

Assignee:

MOTOROLA, INC. - Schaumburg IL

International Classification:

G06F 3/045
H04B 1/10

US Classification:

345174, 375346

Abstract:

Methods, systems and apparatus are provided that implement duty cycle modulation of periodic time-synchronous (PTS) receivers for noise reduction. For instance, when a composite signal is received at a PTS receiver, the composite signal includes an input signal and a noise signal. The composite signal is input to a transmission gate of the PTS receiver. The PTS receiver also receives a gating control input signal that turns the transmission gate on and off. A duty cycle controller adjusts a variable duty cycle of the gating control input signal applied to the transmission gate to output an output signal from the transmission gate such that one or more components of the noise signal present in the composite signal is/are reduced in the output signal that is output by the transmission gate.
