    • An apparatus of a Harmonic Rejection Mixer (HRM) for removing a harmonic component and an operating method thereof are provided. The HRM includes a Local Oscillator (LO), at least one frequency converter, at least two mixers, at least one phase converter, and a combiner. The LO generates an LO signal. The at least one frequency converter multiplies the LO signal using different variables to provide the same to at least two mixers. The at least two mixers convert a frequency band of an input signal using the LO signal provided from the LO and the at least one frequency converter. The at least one phase converter controls a phase of an output signal of at least one other mixer excluding one of the at least two mixers. The combiner combines an output signal of the one mixer with an output signal of the at least one phase converter.
    • 提供了用于去除谐波分量的谐波抑制混频器(HRM)的装置及其操作方法。 HRM包括本地振荡器(LO),至少一个变频器,至少两个混频器,至少一个相位转换器和组合器。 LO产生LO信号。 所述至少一个频率转换器使用不同的变量乘以LO信号,以向至少两个混频器提供相同的信号。 至少两个混频器使用从LO和至少一个频率转换器提供的LO信号来转换输入信号的频带。 所述至少一个相位转换器控制除了所述至少两个混合器中的一个以外的至少一个其它混合器的输出信号的相位。 组合器将一个混频器的输出信号与至少一个相位转换器的输出信号相结合。

    • A drum type washing machine includes an annular recess formed in the front cover such that the annular recess is located immediately adjacent to a wall of the drum body; and a ball balancer including an annular-shaped racer having a closed internal space in which a plurality of balls and viscous oil are accommodated. The annular-shaped racer includes first and second injection molded members joined to each other to form the closed internal space. The ball balancer is supported by the annular recess formed in the front cover of the drum, and the ball balancer is configured to be attachable to the drum with the viscous oil and the plurality of balls already in the ball balancer.

    • Disclosed herein is a washing machine that is capable of increasing a frictional force between an outer diameter of a rotary shaft and an inner race of a bearing to prevent the sliding between the rotary shaft and the bearing due to a gap between the outer diameter of the rotary shaft and the inner race of the bearing, thereby preventing creep noise from the rotary shaft. The washing machine includes at least one elastic member disposed between the outer diameter of the rotary shaft and the inner race of the bearing to prevent noise due to the sliding between the rotary shaft and the bearing.

    • An apparatus and a method for improving communication sound quality in a mobile terminal in order to remove a neighboring noise that occurs together with a user's voice signal in a mobile terminal by discriminating signals occurring at different distances using two microphones and removing a noise. The mobile terminal preferably includes a first microphone, a second microphone, and a voice processor. The first microphone receives a voice signal occurring at a closer distance from the mobile terminal and a voice signal occurring at a longer distance from the mobile terminal. The second microphone receives only a voice signal occurring at the long distance. The voice processor discriminates between the signal occurring at the long distance and the signal occurring at the close distance by receiving voice signals received via the first microphone and the second microphone at different phases.
    • 一种用于改善移动终端中的通信音质的装置和方法,以便通过使用两个麦克风识别在不同距离处发生的信号并消除噪声来消除与移动终端中的用户语音信号一起出现的相邻噪声。 移动终端优选地包括第一麦克风,第二麦克风和语音处理器。 第一麦克风接收在距离移动终端更近距离处发生的语音信号,以及距离移动终端更远的距离发生的语音信号。 第二麦克风仅接收长距离发生的语音信号。 语音处理器通过接收经由第一麦克风和第二麦克风在不同相位接收的语音信号来鉴别在长距离发生的信号和在近距离发生的信号。
