Description

technical field [0001] The present invention refers to an analog processing device for a data transmission device, especially an analog processing device for transmitting voice and audio signals. Background technique [0002] With the advancement of communication technology and the public's demand for mobile communication and high-speed transmission, more and more portable electronic products such as mobile phones, notebook computers, etc., have hardware above the third generation mobile communication (3G) specifications, allowing users to enjoy high-quality voice and data transmission services. A high-speed data transmission device such as a wireless data transmission card (Data Card) is connected to a notebook computer through a common PCMCIA or USB slot interface for data transmission. [0003] However, although the wireless data transmission card supports hardware specifications above 3G, the functions of the wireless data transmission card often cannot be fully utilize...
