摘要:
An anti-feedback device includes an anti-feedback filter provided in a closed loop. The anti-feedback device down-samples a signal of specific band selected from an output signal of an adaptive target signal transfer system and a signal of the same band selected from an input signal of the transfer system, and a filtering coefficient of the adaptive filter is updated by use of the down-sampled signals. 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.

摘要:
A howling suppression apparatus suppresses a howling caused in an acoustic system including a sound collection device and a sound emission device. An estimation part generates an estimated signal by estimating a feedback sound reaching the sound collection device from the sound emission device. An adjustment part generates an estimated signal by adjusting the estimated signal. A spectrum subtraction part generates an acoustic signal using a result of subtracting a frequency spectrum of the estimated signal from a frequency spectrum of an acoustic signal. A filter part generates an acoustic signal by suppressing a component of a frequency band including a howling frequency F among the acoustic signal. An acoustic signal in which the acoustic signal is amplified by an amplifier is supplied to the sound emission device.

摘要:
A multilayer ceramic electronic component comprising an element body in which a dielectric layer and an internal electrode layer are stacked. The dielectric layer is constituted from a dielectric ceramic composition including; a compound having a perovskite structure expressed by a formula of ABO3 (A is at least one selected from Ba, Ca, and Sr; B is at least one selected from Ti, Zr, and Hf); an oxide of Mg; an oxide of rare earth elements including Sc and Y; and an oxide including Si. The dielectric ceramic composition comprises a plurality of dielectric particles and a grain boundary present in between the dielectric particles. In the grain boundary, when content ratios of Mg and Si are set to D(Mg) and D(Si) respectively, D(Mg) is 0.2 to 1.8 wt % in terms of MgO, and D(Si) is 0.4 to 8.0 wt % in terms of SiO2.
