According to different signal modes, communication can be divided into analog communication and digital communication. What is analog communication? For example, in telephone communication, the electrical signals transmitted by users online change with the size of their voice. This changing electrical signal is continuous in both time and amplitude, and is called an analog signal. The communication method of transmitting analog signals on user lines is called “analog communication”.
Digital signals are different from analog signals in that they are a combination of discrete and pulse free signals, which represent the digital information of the load. Telegram signals belong to digital signals. The most common digital signal nowadays is a waveform with only two amplitude values (represented by 0 and 1), called a “binary signal”. Digital communication “refers to the use of digital signals as carriers to transmit information, or the use of digital signals to digitally modulate the carrier before transmission.
