Practice Other Topics from Communication Systems
This topic helps us learn the different elements of the communication system with the help of a figure and also the drawbacks of the system. The three main parts of the communication system are transmitter, communication channel and a receiver.
In this topic, we will discuss different signals, the frequency ranges, and the bandwidth of signals. It explains the transmission medium and its bandwidth. The table given here mentions the frequency range allocated to several broadcasts.
The topic discusses several modes of propagation of electromagnetic waves through the atmosphere. It consists of three modes, i.e., ground-wave, sky wave and space wave propagations with the help of a figure.
This topic guides us through the concept of modulation and demodulation, its need, and types. It also includes the advantages and disadvantages of frequency modulation and the most used demodulator known as the p-n diode detector.
In this topic, we will learn about the global network known as the Internet, its origin, and its uses in brief. It also covers the mobile network, the global positioning system known as GPS, and their uses in our day-to-day life.
