    • A method and apparatus for communicating within a wireless microphone system having a plurality of audio channels. The method includes the steps of dividing a small block of radio frequency spectrum associated with a single television broadcast channel into a plurality of at least 20 contiguous subchannels that are also contiguous with the boundaries of the television broadcast channel where each of the subchannels is less than 75 kHz and transmitting an audio signal from a microphone transmitter on one the plurality of subchannels through a transmitter with a radio frequency isolator or other means for suppressing intermodulation energy coupled to an antenna, the radio frequency isolator having a bandwidth no larger than any one of the plurality of divided subchannels; and receiving the audio signal through a microphone receiver.
    • 一种用于在具有多个音频通道的无线麦克风系统内进行通信的方法和装置。 该方法包括以下步骤:将与单个电视广播频道相关联的无线电频谱的小块划分成多个至少20个连续的子信道,其中每个子信道也与每个子信道小于的电视广播信道的边界相邻 75kHz,并且通过具有射频隔离器的发射器或用于抑制耦合到天线的互调能量的其他装置,从多个子信道中的一个子信道上传输来自麦克风发射机的音频信号,所述射频隔离器具有不大于 多个分割子信道; 并通过麦克风接收器接收音频信号。

    • A potentiometer has a case, a housing, a base and a rotor rotatably arranged in the chamber of housing. The housing is provided with a pair of projections on both side walls thereof and two pair of corner projections at four corners thereof respectively while the case has a pair of bent long legs in which holes are defined to receive the side wall projections of the housing and a pair of bent short walls are arranged to cover the top of the housing. The case may be pushed down upon the housing with the pair of bent long legs thereof being slid down into vertical grooves arranged between the corner projections of the housing until the side wall projections of the housing are slidingly snapped into the holes of the case and thus, the case and the housing may be assembled in one operation. Two end walls of an arcuate portion of a narrow strip are arranged on the surface of the rotor and abut alternatively against two vertical walls of a rectangular strip arranged inside the housing hole and located adjacent a collector element of the base, whenever the rotor rotates in a clockwise or counter-clockwise direction.
    • 电位器具有可旋转地布置在壳体的腔室中的壳体,壳体,基座和转子。 壳体在其两个侧壁上设有一对突起,在其四个角处设有两对角突起,同时壳体具有一对弯曲的长腿,其中限定孔以容纳壳体的侧壁突起, 布置一对弯曲的短壁以覆盖壳体的顶部。 壳体可以被推下到壳体上,其一对弯曲的长腿被向下滑入设置在壳体的角突起之间的竖直凹槽中,直到壳体的侧壁突起滑动地卡入壳体的孔中,因此 ,壳体和壳体可以在一个操作中组装。 窄条的弧形部分的两个端壁布置在转子的表面上,并且每当转子旋转时,交替地抵靠布置在壳体孔内部并位于基座的集电器元件周围的矩形条的两个垂直壁 顺时针或逆时针方向。
