ANALOGUE communication we cannot get some paramanent value
but in DIGITAL we can having only 2 possibalities that is 0
or 1 but in anlogue the value will be varry by using
sampling theorm we can get varrying some more constant
value ..

Answer / sigma 6

Disadvantage: Analog signals are prone to noise and when
lost (fades and blockages etc.)it cannot be recovered
anymore, limited in capacity.
Advantage: Analog signals are true representation of the
original signal, easy to implement, real time transmission.

Disavantage: Digital signals requires high BER reliability
requirements, not real time, difficult to implement.
Advantage: transmission rebustness under adverse
conditions, high capacity, lost informations can be
recovered, higher noise tolerance, complex modulations can
be impelemented easily,multiplexing techniques are easy to
implement.

Answer / mahadev pawase
