One of the most important parts of the data transmission systems is processing of the signals. In the primary models of this system, all these processes were done in an analog format. Because of this, the volume and the price were high. But in this model of system, however, all the processes are done digitally in which case the precision is high and also it contains all the abilities of the digitized systems. Some of the major changes in the structure of the system are: low cost, high precision, flexibility, etc.
