Question

Explain how the data rate over a channel can be increased, without increasing the bandwidth? What is the disadvantage of this approach?

Answer 1

hello bro your question is available on Google

Answer 2

The data rate over a channel can be increased, without increasing the bandwidth by:

• The data rate through a channel is increased by the help of Nyquist Bit rate without even increasing the bandwidth of the data transmission even with a single bit.

• $BitRate = 2\times Bandwidth \times log_2(L)$.

• In this process we will increase the rate of the data transmission through one place to another place with the equation of the rate of the bit is equal to twice the product of bandwidth and the logarithm of second base of the signal level.

• The disadvantage due to this approach is it produces additional unnecessary sound.
