Please give me suggestion. Name required. Email required. Analog radio bandwidth has recently shrunk from 25 kHz to With digital technology, channel bandwidth can be compressed to a spectrum-efficient 6. In regard to TDMA and digital technology, the The RF spectrum efficiency is achieved when two voice channels share time to create a 6.

Floppy disk is a magnetic storage medium for a computer system. This article gives information about the advantages and disadvantages of a f TDMA occupies a channel but it allows two users to occupy the same channel at what appears to them to be the same time.

An analogy could be the still shot frame rates in cinema, where at around 30 frames per second it gives the illusion of continuous movement but it is actually a time shuttling exercise. With a 2-time slot TDMA system, two users can share the same frequency in the following manner: User 1 gets to use the frequency for a very short fixed period of time, perhaps 50 milliseconds.

Then the channel reverts to user 2 who gets 50 milliseconds. Then it cycles again back to user one who gets a further 50 milliseconds, and so on and so forth. This process is so fast that each user thinks they have exclusive use of the frequency channel. With 2-time slot TDMA, in order to have more than two conversations going on at the same time then another radio channel is needed. If it is another 2-time slot TDMA channel then two frequencies can simultaneously support four conversations; or apparently simultaneously, because of this shuttling exercise.
