Block diagram digital communication system. The block diagram of a communication system will have five blocks including the information source transmitter channel receiver and destination blocks. Block diagram of communication system i information source. After watching this video you will be able to understand the working of source coding decoding channel. Block diagram of digital communication system 2.

Block diagram of a digital communication system. As we know a communication system serves to communicate a message or information. A digital communication system consists of six basic blocks. The functional blocks at the receiver perform the reverse process to retrieve the original message 2.

Power of a signal. Digital communication system 1. The communication medium can be conducting wires cables optical fibres or free space. The functional blocks at the transmitter are responsible for processing the input message encoding modulating and transmitting over the communication channel.

In this video i have explained block diagram of digital communication system by following outlines. The basic elements of a spread spectrum digital communication system with a binary information sequence at its input at the transmitting end and its output at the receiving end. Following is the diagrammatic representation. A transducer is a device which converts one form of energy into another form.

Hi friends in this lecture a block diagram of digital communication system is explained. The block diagram of spread spectrum digital communication is shown in above fig. The information comes from the information source which originates it. This is the most common information source in a communication system.

Here we will talk on its feature. The line communication systems use the communication medium like the simple wires or cables or optical fibres. Digital transmission system block diagram sreejith hrishikesan february 17 2019 many of the signals used in modern communication are digital for example the codes for alphanumeric characters and the binary data used in computer programs. These two are connected to two band pass filters.

In addition digital techniques are often used in the transmission of analog signals. The fsk signal input is given to the two mixers with local oscillator circuits. More or large bandwidth doesn t mean it s conveying more information to its users.
