5 DIFFERENCE BETWEEN BASE BAND ,CARRIER AND MODULATED SIGNAL

-

 BASE BAND SIGNAL :

  1. The message signal which is coming form an information source is called base band signal
  2. it is a low frequency signal
  3. it is the output of information source
  4. it combines with the carrier to generate modulated signal

CARRIER SIGNAL :
  1. The signal which is used to carry message signal is called carrier signal
  2. it is a high frequency signal
  3. it is the output of oscillator
  4. it combines with the message to generate modulated signal
MODULATED SIGNAL :
  1. The output of modulator is called modulated signal
  2. it is a high frequency signal
  3. it contains both message information and carrier properties
  4. it is the output of modulator

  BASIC ELEMENTS OF COMMUNICATION SYSTEM      INFORMATION SOURCE :   It produces message signal which we want to send.   It converts message signal to electrical signal .(it is also called as input transducer)     TRANSMITTER :   It converts the message signal to suitable form of propagating signal over communication channel.   The process of conversion is possible by modulation. And finally sends the signal through the channel.     CHANNEL :   The path for transmitting a signal is called channel.    It is a medium between transmitter and receiver ( wire / wireless ),use for signal transmission.                      NOISE :      The unwanted form of signal energy is known as noise.        It enters the communication system through channel.          RECEIVER :     The main fun...
