   Introduction to Communication System
  What is communication?
  It's  the  process  in  which  information  is  transfer  from  one 
  point  in  space  and  time  called  the  source  to  another  point 
  destination.
  What is a communication system?
  It's the group of mechanism that provides the information link 
  between source and destination.
  What is the purpose of a communication system?
  The  purpose  of  a  communication  system  is  to  transmit 
  information signals through a communication channel.                  Source: https://jooinn.com/communication-

  Fundamentals of Communication system:
  Frequencies 
  Frequency is measured in hertz (Hz), equivalent to cycles per second: thus 1 Hz is 1 c/s. The 
  electromagnetic spectrum consists of frequencies from just above 0 Hz to ∞ Hz. The frequency 
  spectrum  is  broken  up  into  different  segments  which  indicate  the  usage  for  particular 
  frequency range as shown in table below.
                                                                                                   5

                          Common Frequency ranges
    The frequency band of 20 Hz to 21 kHz is the total band that the human ear can hear. 
   Types of Signal There are only two different types of signal that are processed, transmitted and 
   received  by  telecommunication  equipment. These  are  analogue  and  digital.  Each  type  has 
   individual characteristics.
