Transmitter. What are the goals of the digital communication system? Digital communication system is a system through which we can share different type of data worldwide. The process of changing the amplitude of the signal wave by impressing or superimposing it on a high-frequency carrier wave, keeping its frequency constant is called amplitude modulation. Telecommunication Network Diagrams solution extends ConceptDraw PRO software with samples, templates, and great collection of vector stencils to help the specialists in a field of networks and telecommunications, as well as other users to create Computer systems networking and Telecommunication network diagrams for various fields, to organize the work of call centers, to design … 2. It can be in the form of audio, video, temperature, picture, pressure, etc. External sources include interference, i.e. We can broadly classify the channels into two parts-. It acts as an energy converter (transducer at the receiving end) as it converts the electrical signal back into the audio signal (non electrical form). As we discussed that the input transducer is used to convert the non electrical signal into electrical signal. There are several specifying components in contrary to Figure 1 – the communication channels are the optical fibre cable, and the optical transmitter and optical receiver. Noise is an unwanted random signal that interferes with the original message signal. A channel refers to a physical medium such as wire, cables, space through which the signal is passed from transmitter to the receiver. Out of the following, which is not an essential element of a communication system? This post is about the generation of amplitude modulation. The function of the transmitter section is to process the electrical signal from different … The destination also works as a transducer at the receiving end.

A repeater receives the transmitted signal, amplifies it and send it to the next repeater without distorting the original signal. Because it is much easier to process electrical signals in comparison to other non electrical signals. Repeaters are placed at different locations in between the transmitter and receiver. The owner of this blog will not be responsible for any losses, injuries, or damages from the display or use of this information. An antenna is basically a metallic object, often a collection of wires. Let’s consider in detail how this system works. The disturbance or distortion in the transmission and processing of message signals is called? So, to reduce the block diagram, proper logic must be used. Telecommunication Network Diagrams solution extends ConceptDraw DIAGRAM software with samples, templates, and great collection of vector stencils to help the specialists in a field of networks and telecommunications, as well as other users to create Computer systems networking and Telecommunication network diagrams for various fields, to organize the work of call centers, to design … Broadcast and telephone transmission are common examples of Analog technology. An Antenna is a structure or a device that is radiate and receive electromagnetic waves. When the signal is propagating for a longer distance through a medium, depending on the length of the medium the initial power decreases. 2. The single-valued function of time that carries the information. It is easier and better to derive the transfer function of the control element connected to the system, separately. In the receiver, the Demodulation (detection) of the modulated signal takes place. In the demodulation process the original message signal is recovered back from the modulated signal. A channel is the medium through which the message travels from the transmitter to the receiver. Optical Fiber Communication System Block Diagram Electrical Transmitter contains electrical stage which drives an optical source to give modulation of light wave carrier. interference from nearby transmitted signals (cross talk), interference generated by natural source such as lightning, solar or cosmic radiation, from automobile generated radiation, etc. For long-distance transmission of data, will require a larger amount of data. The electronic circuit or device that increases the amplitude or the strength of the transmitted signal is called an amplifier. The writers of Block Diagram Of A Communication Satellite System have made all reasonable attempts to offer latest and precise information and facts for the readers of this publication. Example- microphone is a transducer at the input side, that converts audio signal (non-electrical) into electrical signal. It is better than deficient than amplitude modulation because it eliminates noise from various sources. This all processing is done to just ease the transmission of signal through the channel. As the name implies, a Block Diagram is a drawing illustration of a system whose major parts or components are represented by blocks.
