20150341124 | ASYNCHRONOUS RECEIVER-TRANSMITTER CIRCUIT AND WASHING MACHINE INCLUDING THE SAME - An asynchronous receiver-transmitter circuit which compensates for an output signal so as to be the same as an input signal upon an asynchronous communication, and a washing machine including the same. The asynchronous receiver-transmitter circuit includes a photo-coupler turned on by an applied input signal to provide an output signal; and a compensation part configured to compensate for a time required while the output signal arrives at a high value to correspond to a time required while the output signal arrives at a low value. | 2015-11-26 |
20150341125 | SYSTEMS AND METHODS FOR MULTI-RATE DIGITAL SELF-INTERFERENCE CANCELLATION - A system for multi-rate digital self-interference cancellation including a signal component generation system coupled to a digital transmit signal of a communication system that generates a set of signal components from the digital transmit signal; a multi-rate adaptive filter that transforms the set of signal components into a digital self-interference cancellation signal, according to a transform configuration, to form an interference-reduced receive signal; and a transform adaptor that dynamically sets the transform configuration in response to changes in the interference-reduced receive signal. | 2015-11-26 |
20150341126 | METHOD AND DEVICE FOR SUPPRESSING HARMONIC SIGNALS - A method for suppressing harmonic signals includes: mixing a first local oscillation signal with an input signal to obtain a first output signal, and mixing a second local oscillation signal with the input signal to obtain a second output signal, the first output signal including an n-order harmonic signal, n being a positive integer greater than 1; and adding the first output signal and the second output signal to suppress the n-order harmonic signal in the first output signal. The first local oscillation signal and the second local oscillation signal have different mark-space ratios but a same oscillation frequency. | 2015-11-26 |
