A modem is an electronic device that modulates a digital signal to transmit an analog signal, and demodulates the received analog signal to obtain a digital signal. Its goal is to produce an analog signal that is easy to transmit, and the original digital signal can be restored through decoding. According to different applications, modems can use different ways to transmit analog signals, such as using fiber optics, radio frequency radios or telephone lines.
