Digital communication 1/3/2018 objectives • discuss the advantages of digital communication • calculate the minimum sampling rate for a signal and explain the necessity for sampling at that rate and above • describe pcm and calculate the number of quantizing levels, the bit rate, and the dynamic range for pcm systems. How can the answer be improved. No the great disadvantage of digital systems is that they are not continuous, yet they have to deal with analog data it is impossible for a system that is discrete by definition to sample a continuous signal and retain all of its information similarly, it is also impossible to fully reconstruct. Signal analog signal is a continuous signal which represents physical measurements digital signals are discrete time signals generated by digital modulation example human voice in air, analog electronic devices computers, cds, dvds, and other digital electronic devices technology analog.

Advantages of digital communication and signal
Some of the advantages of digital communication are- 1)digital signals carry more information per second than analogue signals this is the same whether optical fibres, cables or radio waves are used 2)digital signals maintain their quality over long distances better than analogue signals.
So first let's start with the advantages of digital communication when analog signal is converted into digital signal # in digital communication. The advantages of digital signals are increased capacity, better quality and the signals can be stored and processed by computers increased capacity means that. A digital signal is a discrete form digital signals are represented by square wave in digital signals 1 is represented by having a positive voltage and 0 is represented by having no voltage or zero voltage. Digital versus analog two-way radio communications the shift to digital radio from analog has there are more advantages of digital two way radios in. The benefits and advantages of digital signal from it and there is no real-time communications” digital signal other advantages of dsp. 1) digital communication systems are cheaper to implementit is possible to manufacture very high speed embedded circuits due to advancements in vlsi technology in cost effective manner such circuits are used in digital communications 2) digital communication allows regenaration the digital signal in long distance. Advantages of digital signals over analog signal the advantage of digital signals are these are more accurate and reliable than analog signal.
The followings are few advantages and disadvanatages of analog vs digital communication1the first advantage of digital communication against anlog is it's noise immunityin any transmission path some unwanted voltage or noise is always present which cannot be eliminated fullywhen signal is transmitted this noise gets added to the. Analog vs digital communication advantages of digital communication: a) in a digital communication the signal is digitised to a stream of 0 s and 1 s. Digital communication is adaptive to other advanced branches of data processing such as digital signal processing, image processing and data compression, etc disadvantages due to analog to digital conversion, the data rate becomes high therefore more transmission bandwidth is required for digital communication. The advantages of an analog recording system are the absence of aliasing distortion and quantization noise the wide dynamic range and performance in overload conditions digital systems, meanwhile, have better audio recording quality and an easier integration to personal computers and software applications. And what is a digital signal what are the advantages and disadvantages of analog communication and digital communication advantages of digital - less. What are advantages and disadvantages of digital communication advantages of digital communication are advantages and disadvantages of digital. The advantage of analog over digital or vice versa , is dependent on the input information type and / or signal amplitude where applicable , also on what the application is an d other considerations like information / signal processing , storage , etc.
