The filter controller controls a filtering characteristic of the anti-feedback filter so that a peak gain of a frequency of an amplitude characteristic within a specific band of a closed loop determined from the filtering coefficient of the adaptive filter is suppressed. Moreover, the filter controller estimates a gain of the closed loop outside the specific band from the amplitude characteristic in the specific band and controls the amount of suppression of the anti-feedback filter, outside the band in accordance with a result of estimation. | 07-01-2010 |

20130082951 | TOUCH SENSOR, AND CONTROLLER PROVIDED WITH THE TOUCH SENSOR - One electrode and another electrode adjoining an upper end region of the one electrode in an operating direction of a fader sensor are divided by a boundary line extending zigzag in a generally M shape transversely relative to the operating direction, so that upper and lower apex portions of the one electrode and the other electrode bite into each other. Similarly, the one electrode and another electrode adjoining a lower end region of the one electrode each other are divided by a boundary line extending zigzag in a generally M shape transversely relative to the operating direction. As a finger touches the fader sensor, the finger simultaneously touches the three electrodes, and corresponding output signals are output therefrom. A weighted average of the output signals is calculated so that position information of the finger having touched the sensor can be acquired with a high resolution. | 04-04-2013 |

20090027121 | Class D amplifier circuit - A pulse monitor circuit detects the presence or non-presence of the output pulses output from an output stage circuit. The pulse monitor circuit outputs an up signal to the up/down counter when the output pulses do not exist at all and outputs a down signal to the up/down counter when the output pulses exist. The up/down counter outputs a signal for increasing the delay amount of a delay amount variable circuit when a count value is large, that is, when the output pulses disappear. In contrast, when the count value is small, that is, when the output pulses exist, the counter outputs the signal for reducing the delay amount of the delay amount variable circuit. | 01-29-2009 |
