Fig.1 shows the block diagram of a general communication system, in which the different functional elements are represented by blocks. Fig 1. The essential components of a communication system are information source, input transducer, transmitter, communication channel, receiver and destination. Now, we shall discuss the functioning of these blocks.
The input transducers commonly used in the communication systems are microphones, TV etc. Transmitter. The function of the transmitter block is to convert the electrical equivalent of the information to a suitable form ; It increases the power level of the signal. The power level should be increased in order to cover a large range.
Block Diagram of munication Systems The block diagram given below represents the flow of the signal from the source to the destination. The role of every device and arrangement discussed above is better understood.
Block diagrams are essentially a very simple format of diagrams. A variety of commonly used shapes and connecting lines, rules of construction and actions pertaining to them, make Block diagram a versatile and flexible tool for many forms of industry.
Automatic Wireless Health Monitoring System in Hospitals for Patients; Thus, this is all about block diagram and explanation of RF transceiver, includes what is RF module, RF transmitter, RF receiver, block diagram of RF transceiver module and applications of RF transceiver. We hope that you have got a better understanding of this concept.
Basic block in transmitter are: Amplifier,Oscillator,Mixer. 4.Channel: The communication channel is the medium used for transmission of electrical signal from one place to other.
22.451 Dynamic Systems – Block Diagrams Block Diagram Representation A system transfer function describes the typical input output. Additional dissipative forces can be included as part of a closed loop system. F(s) X(s) ms cs k 1 2 Coulomb Damping − µN
The receiver consists of a similar sequence of block diagrams. Whatever was done in the transmitter will be undone in the receiver. For example, modulation in TX will be matched by Demodulation in RX, A to D in TX will be undone by D to A in the receiver and so on. Application Areas of munication System
The block diagram is to represent a control system in diagram form. In other words, practical representation of a control system is its block diagram. It is not always convenient to derive the entire transfer function of a complex control system in a single function.
Block diagrams consist of a single block or a combination of blocks. These are used to represent the control systems in pictorial form. Basic Elements of Block Diagram. The basic elements of a block diagram are a block, the summing point and the take off point.
