10 ADVANTAGES AND DISADVANTAGES OF DSB-SC, SSB-SC

-



ADVANTAGES AND DISADVANTAGES OF DSB-SC :

ADVANTAGES OF DSB-SC:
  1. It saves more power than AM
  2. less bandwidth required compare to AM
  3. low power consumption
  4. DSB-SC generation is simple compare to AM
DISADVANTAGES OF DSB-SC :
  1. bandwidth required is same as AM
  2. Product detector required for demodulation
  3. detection of DSB-SC signal is complex

 ADVANTAGES AND DISADVANTAGES OF SSB-SC :

ADVANTAGES OF SSB-SC:
  1. Less noise in SSB-SC
  2. It saves more power than AM & DSB-SC
  3. less bandwidth required compare to AM & DSB-SC
DISADVANTAGES OF SSB-SC :
  1. Complex process of generation and reception IN SSB-SC
  2. SSB-SC not used for transmission of good quality of signals

  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...
