20080240464 | METHOD FOR OUTPUTTING AUDIO SIGNALS AND AUDIO DECODER - Method for outputting an audio signal to an audio output, comprising outputting a first audio signal to said audio output; providing a second audio signal; determining a point in time, wherein at said point in time said first audio signal or a derivative of said first audio signal or a derivative of said second audio signal is essentially equal to zero; switching, at said point in time, said audio output from outputting said first audio signal to outputting said second audio signal. | 10-02-2008 |
20080252368 | CIRCUIT AND METHOD FOR PROCESSING AN INPUT SIGNAL - Circuit for processing an input signal based on at least one reference signal, comprising a phase locked loop demodulator configured to receive a speed control signal and said input signal and further configured to follow a frequency and/or a phase of said input signal at a speed, wherein said speed depends on said speed control signal; and a reference signal detector configured to determine said at least one reference signal and to set said speed by outputting said speed control signal to said phase locked loop demodulator, wherein, if said reference signal detector detects said at least one reference signal, said reference signal detector decreases said speed. | 10-16-2008 |
20090122203 | DEMODULATOR, METHOD AND RECEIVER FOR DEMODULATION - Demodulator for demodulating an input signal, comprising a complex-valued equalizer configured to equalize complex valued echoes within said input signal, wherein said complex-valued equalizer outputs a complex valued equalized signal; and a PLL circuit ( | 05-14-2009 |
20090244384 | ANALOG TV BROADCAST SIGNAL RECEIVING APPARATUS AND ANALOG TV BROADCAST SIGNAL DEMODULATING APPARATUS - Disclosed herein is an analog television broadcast signal receiving apparatus including: a tuner section configured to convert an analog television broadcast signal into a predetermined intermediate frequency band signal; a demodulation circuit section configured to obtain a picture output signal and a sound intermediate frequency signal from the predetermined intermediate frequency band signal coming from the tuner section; a picture processing circuit section configured to convert the picture output signal into a display-ready picture signal; a sound demodulation processing circuit section configured to demodulate the sound intermediate frequency signal; and a control section. | 10-01-2009 |
20110242429 | METHOD AND RECEIVER FOR DEMODULATION - A method of demodulation includes determining samples of a modulated analogue audio signal; determining at least one distorted sample of the samples depending on the signal quality of the modulated analogue audio signal; and replacing the distorted sample. | 10-06-2011 |
20120147938 | COMMUNICATIONS SYSTEM USING ADAPTIVE FREQUENCY NOTCHING - A communications system includes a receiver unit connected with a transmission channel. The receiver unit determines a signal power of a first communications signal received over the transmission channel. A transmitter unit is connected with the transmission channel and transmits a second communications signal, wherein a gain of the communications signal being output by the transmitter unit is controllable. A control unit controls the gain of the transmitter unit in response to the determined signal power. At the receiver unit, detection of broadcast signal ingress during data communication is improved and methods for avoiding disturbances between coexisting communications systems may become more reliable. Different distances between successive training symbols suitable for channel estimation may be provided to enhance the noise measurement. | 06-14-2012 |
