![]() ![]() This may be an opinion, attitude, feelings, views, orders, or suggestions. This is the subject matter of the communication. The person who intends to convey the message with the intention of passing information and ideas to others is known as sender or communicator. Seven major elements of communication process are : Filtering is another important function at the receiver. These also include demodulation and decoding to reverse the signal procession performed at the transmitter. Receiver operations include amplification to compensate for transmission loss. The receiver operates on the output signal from the channel in preparation for delivery to the transducer at the destination. So, the signal power progressively decreases with increasing distance. Every channel introduces some amount of transmission loss or attenuation. ![]() It may be a pair of wires, a coaxial cable, or a radio wave or laser beam. The transmission channel is the electrical medium that bridges the distance from source to destination. Signal processing for transmissions almost always involves modulation and may also include coding. The transmitter processes the input signal to produce a suitable transmitted signal suited to the characteristics of the transmission channel. Each parts plays a particular role in signal transmission, as follows: There are three essential parts of any communication system, the transmitter, transmission channel, and receiver. ![]()
