Multiplexing techniques
12. Describe the Multiplexing techniques for digital signal transmission.
Multiplexing is a technology to transfer digital or analog data in daily use devices like telephone and television. Here, we discuss the various multiplexing technologies used for data transmission.
Multiplexing is a method of combining multiple analog massage signals or digital data streams into one signal. The objective of this technology is to share an expensive medium for transmitting multiple signals. Actually, the low-level communication signals are divided into high-level logical channels using this technology. Furthermore, each channel is then used for transmitting one message signal or data stream.
Time Division
The time division multiplexing technology uses a multiplexor to collect and store incoming signals from the slow lines connected to it by distributing a time slot on the fast link to each in turn. The message signals are sent one after another. They are then …
