Question

Difference between multiplexing and spread spectrum

Answer 1

Spread spectrum involves the transmission of either digital or analog data with the help of an analog signal.Spread spectrum has more resistance to natural noise, interference, and jamming that makes it a preferred choice for secured communications when compared to multiplexing

Answer 2

Different signals transferred to one signal is the multiplexing process but in the spread spectrum signal is transferred with large bandwidth than its original.

• Using multiplexing number of signals can be transferred through a link at a time.
• The device used for this process is known as a multiplexer.
• In real life, telephones are an example of multiplexing.
• Varies of calls are pa-ss through a single link.  
• In the spread spectrum, one signal with a particular bandwidth is delivered with a higher frequency than its original one.
• Bar co-de scanners, microphones, and wireless LAN are the real-life application of the spread spectrum.
• Interference will not be there in the spread spectrum.
