    • PURPOSE: An apparatus is provided to improve the signal-to-noise radio of a citizen's band (CB), a 10 meter radio receiver and scanner radio receiver. CONSTITUTION: A compander circuit (30) is used in both the transmitting and receiving portions of the radio. Demodulated incoming audio signals are expanded by the compander circuit (30) to increase the dynamic range of incoming audio signals. Outgoing audio signals from a microphone (36) are compressed by the compander circuit (30) to decrease the dynamic range of the outgoing audio signals before they are amplified and transmitted.
    • 目的:提供一种改善公民乐队(CB),10米无线电接收机和扫描仪无线电接收机的信噪比无线电设备。 构成:在无线电的发送和接收部分中使用压缩扩展电路(30)。 被解调的传入音频信号由压缩扩展电路(30)扩展,以增加输入音频信号的动态范围。 来自麦克风(36)的输出音频信号由压缩扩展电路(30)压缩,以在输出音频信号被放大和发送之前降低其输出音频信号的动态范围。

    • PURPOSE: A voice storage device for a mobile communication terminal is provided to outputs selectively a stored voice by compressing and storing only a valid voice information. CONSTITUTION: A voice storage device for a mobile communication terminal comprises an input portion(100), a coder/decoder portion(200), a vocoder portion(300), a control portion(400), a memory portion(500), and LCD portion(600). The input portion outputs a corresponding command signal. The code/decoder portion converts an analog voice signal to a PCM data, or the PCM data to the analog voice signal. The control portion controls outputs a control signal to determine the compression and storage for the receives voice and the transmission or the storage for a compressed signal. The memory portion stores the compressed voice information. The LCD portion displays a storage state of voice information.
    • 目的:提供一种用于移动通信终端的语音存储装置,通过压缩并仅存储有效的语音信息来选择性地输出存储的语音。 构成:用于移动通信终端的语音存储装置包括输入部分(100),编码器/解码器部分(200),声码器部分(300),控制部分(400),存储部分(500)和 LCD部分(600)。 输入部分输出相应的命令信号。 代码/解码器部分将模拟语音信号转换为PCM数据,或将PCM数据转换为模拟语音信号。 控制部分控制输出控制信号以确定用于接收语音的压缩和存储以及用于压缩信号的传输或存储。 存储器部分存储压缩的语音信息。 LCD部分显示语音信息的存储状态。
