The output signal data of the transmitter can be divided into analog signal and digital signal according to the form of presentation. Analog signals refer to information expressed in continuously varying physical quantities, such as temperature, humidity, pressure, length, current, voltage, and so on. In the process of analog signal transmission, the information signal is first converted into an almost “identical” fluctuating electrical signal (hence the name “analog”), and then transmitted by wired or wireless means, and the electrical signal is received and restored into an information signal through the receiving device. The main advantage of the transmitter’s analog signal is its precise resolution. The transmitter has a higher density of analog signal information. Since there is no quantization error, the true values of physical quantities in nature can be described as closely as possible. Another advantage of using analog signals in transmitters is that analog signals are easier to process than digital signals for the same effect. Digital signal refers to a special set of states to describe the signal, the typical is the signal that is currently represented by the most common binary digits, the reason why binary digits are used to represent the signal, the fundamental reason is that the circuit can only represent two states, that is, the circuit is on and off. There are many advantages of using digital signals for transmission in transmitters, the first of which is that they are particularly resistant to interference. Secondly, the computer also uses digital signals, so that the combination and processing of variable information. Thirdly, the digital signal of the transmitter is easy to store. Since the digital signal is represented by two physical states, 0 and 1, its ability to resist the interference of the material itself and the environment is much stronger than that of the analog signal during the use of the transmitter. In the signal processing of modern technology, digital signals play an increasing role in transmitters.
