Why statistical TDM is considered more efficient than synchronous TDM?
Wiki User
∙ 13y ago
A statistical Time Devision Multiplexing is more efficient than a synchronous TDM because it allocates time slots dynamically on demands and doesm't dedicate channel capacity to inactive low speed lines.

∙ 13y ago1. The throughput efficiency can be improved by allowing the multiple data sources to be packaged in a single frame.
2 When many sources are packaged in a single frame, it is necessary to specify the length of the data for each source. Therefore statistical T.D.M. sub-frame consists of a sequence of data fields. Each data field is labled with an addres and length making it more eficcient in error detection

∙ 11y agothe major difference between both is that the time slot is not same for each sending device.
the wastage of capacity of the multiplexed channel is solved by asynchronous or statistical time division multiplexing.
In synchronous Time division multiplexing their is under utilization of capacity of multiplexed channel. This way cost to multiplex per character increases.

What is the actual term for computer memory sdram?
The actual term for computer memory SDRAM is Synchronous Dynamic Random Access Memory. You can learn more about SDRAM online at the Wikipedia website.
The use of computers in recording business events?
has made the recording process more efficient
Are notebook computers efficient for officer work?
Yes, there are a number of different notebook computers or laptops which are considered to be good for office use. In order to find out more about this, you may need to pay a visit to your local electronic store and see what each brand has to offer.

What are positive and negative effects of recording technology?
smaller, more efficient able to obtain private information.
What happens if you use synchronous motor in ceiling fans?
Synchronous motors are much more efficient at converting electric power into motion. However, the speed of the motor is controlled by the frequency of the electric supply. So a synchronous motor ceiling fan would be much more efficient, but the speed of the fan would not be controllable, unless frequency controlled power supplies (inverter power) are used.
What is synchronous machein?
mainly alternator,synchronous motor comes under the synchronous machine.a synchronous motor is not a self starting motor.if a synchronous motor moves with more than synchronous speed then it acts as a synchronous generator.
Are all hybrid cars energy efficient?
Not all cars are in need of being more efficient depending on what standpoint this is considered. Hybrids, relatively speaking are very efficient cars.
What was considered a strength of the patriots during the American Revolution?
They had a larger and more efficient navy.
Fluorescent light bulbs are considered more efficient because they they?
Lose less energy as heat.
Why is the speed of synchronous motor is more then induction motor?
Synchronous motors run at synchronous speed. An induction motor that has the same number of poles must run at a sub-synchronous speed to create a second magnetic field (a field that is at a different phase angle) to generate torque.
What is the comparative for efficient?
More efficient and most efficient are the comparative and superlative forms of "efficient".
Why the synchronous modems are more costly than the asynchronous modems?
Because they contain clock recovery circuits
Is at the Minnesota zoo do spider monkeys typically weigh more than owl monkeys a statistical question?
Yes, it is.
Why is the metric system considered more efficient to use than the measuring system you use in the US?
it is not as complex and can be changed easily
