Block Diagram Communication System. In the case of a digital source the information source generates a discrete and random message signal that does not change over time. The block diagram explanation is.
I the necessary components of a communication system are an information source input transducer transmitter communication channel receiver and destination. I shows the block diagram of a general communication system in which the different functional elements are represented by blocks. When using an analog source the data is analog and changes over time.
Low pass filter this filter eliminates the high frequency components present in the input analog signal which is greater than the highest frequency of the message signal to avoid aliasing of the message signal.
Narrow spectral width 4. Optical fiber communication system block diagram electrical transmitter contains electrical stage which drives an optical source to give modulation of light wave carrier. 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.
