What are the components of a communication system?
The transmitting device is the function of all kinds of transform and processing of baseband signal, such as amplification and modulation. The channel is the transmission signal. The destination is the recipient of the information, and the corresponding source. Function and transmitting equipment receiving equipment function on the contrary, the received signal processing and noise source is transform. In the channel and focus on the performance of noise scattered in and other places of the communication system.
The communication system generally is composed of three parts: the sender (source and transmission equipment), channel, receiver (destination and receiving device), noise source. The source is the source of information, its role is to transform the original signal into a corresponding electrical signal, namely the baseband signal.
