The main function of the modem is data transmission.Modem is an important device for data transmission between computer and Internet. Through the process of modulation and demodulation, the modem converts the digital signal to the analog signal to realize the efficient transmission of data. Whether in a home network or an enterprise network, modems play an important role. Understanding the working principles and application methods of the modem can help users better use the device and improve the stability and speed of the network connection. Modulation is the process of converting a digital signal into an analog signal. Computer-generated digital signals cannot be transmitted directly over telephone lines or cable networks, so they need to be converted into analog signals via a modulator. Demodulation is the process of converting a received analog signal back to a digital signal. When the modem receives an analog signal from the Internet, it is converted by the modem into a digital signal that the computer can recognize. The demodulation technology corresponds to the modulation technology to ensure the accuracy of data transmission.
