NCERT Solutions for Class 12 Physics Chapter 15: Points to Remember

Below we have provided some of the important points related to Communication systems to help students with their studies:

  • Communication systems are simply a collection of systems/technologies to transmit information in the form of electrical signals or electromagnetic waves.
  • These systems are categorically arranged into three different types on the basis of their uses – media, technology, and application area.
  • Sensors, transducers, emitters, and amplifiers are examples of modern technology used as components in most modern communication devices.
  • Electronic communication is the faithful transformation of a message or information that can be available in the form of an electrical current or voltage travelling from one point to another.
  • Every message signal is made up of different frequency ranges that are critical for the signal’s optimal transmission of information.
  • Any practical communication supports a few frequency ranges.
  • Low-frequency signals cannot travel long distances and must be superimposed with a high-frequency carrier signal to flow smoothly.
