WHAT IS THE DISADVANTAGE OF DIGITAL COmmunication?

Re: COMMUNICATion

the disadvantage of digital communication is loss due to quantisation, speed and bandwidth.....

Re: COMMUNICATion

Digital communication may use processors which dissipates huge power which is not the case in analog communication .

Is this a disadvantage..?? How u r saying digital processor ll dissipates huge power than analog... ??

Re: COMMUNICATion

Ofcourse Microprocessors that has millions of transistors consume power.....

so u r saying , there is no transistor in analog communication systems..????

:idea:

Re: COMMUNICATion

of cource but you will never design a analog system with one million transistors.....

Re: COMMUNICATion

The disadvantage of the Digital Communications is Coverage which able to cover by the system.

**broken link removed**

Points mentioned are
* greater bandwidht (although compression can be used)
* sampling error
* Compatibility with existing analog systems

Re: COMMUNICATion

Hi All....,

Hey guys let's not flex our muscles over petty issues... we are all here to help each other....Right???

The main disadvantage with digital communication is that it is more susceptible to noise than analog. Let's look at it like this...

we have trasmitted same data through analog as well as digital means... at the analog end in the worst case signal may have been drowned in noise and this is avoidable by suitably designing our communication channels, whereas in no case is the data CORRUPT...!!!

This is the case with digital (and some OFCs Also) communication, where in the channels are prone to "cross-talk". This said...now eventhough you may still have a strong enough signal, but even if one bit is corrupted (and more so when that bit is of CRC etc..) it becomes quite difficult to extract the signal.

there is more about this in
