The search “digital marketing” on Google returns over 2 billion (!) results.Īt Convertful, we recognize the need to make this clear, as our product applies only to digital media.īefore trying to apply all types of digital marketing to your business, let’s explore what exactly the term means, what it consists of, and how you can use it to drive your business forward. If you are not sure what exactly digital marketing is, you are definitely not the only one. We probably also feel we should be doing more of it, what with over 4 billion Internet users worldwide.īut how many types of digital marketing are there? Is marketing on social media considered “digital”? What about radio advertising? Or video) that is obtained through a process called quantisation.The digital representation is never the exact signal but it’s most closely approximated digital form.So it’s accuracy depends on the degree of approximation taken in quantisation process.When it comes to digital marketing, it seems we are all familiar with the term. Techniques are available that use the available babdwidth much efficiently than analog communication techniques.Ħ.when audio and video signals are transmitted digitally an AD(Analog to Digital) converter is needed at tansmitting side and a DA(Digital to Analog) converter is again needed at receiver side.While transmitted in analog communication these devices are not needed.ħ.Digital signals are often an approximation of the analog data(like voice Repeaters are neede every 5 to 6 Kms apart.So definitely digital communication is cheaper.Amplifiers also often add non-linearities thatĥ.Bandwidth is another scarce resource.Various Digital communication Resulting in better recovery of actual signal.Incase of analog communication it’s difficult to remove the noise once added to the signal.Ģ.security is another priority of messaging services in modern days.Digital communication provides better security to messages than the analog communication.It can be achieved through various coding techniques available in digital communication.ģ.in a digital communication the signal is digitised to a stream of 0 sĪnd 1 s.So at the receiver side a simple decision has to me made whether received signal is a 0 or a 1.Accordingly the receiver circuit becomes simpler as compared to the analog receiver circuit.Ĥ.Signal when travelling through it’s transmission path gets faded gradually.So on it’s path it needs to be reconstructed to it’s actual form and re-transmitted many times.For that reason AMPLIFIERS are used for analog communication and REPEATERS are used in digital communication.amplifiers are needed every 2 to 3 Kms apart where as Some more explanation of advantages and disadvanatages of analog vs digital communication.ġ.The first advantage of digital communication against anlog is it’s noise immunity.In any transmission path some unwanted voltage or noise is always present which cannot be eliminated fully.when signal is transmitted this noise gets added to the original signal causing the distortion of the signal.However in a digital communication at the receiving end this additive noise can be eliminated to great extent easily The detection of digital signals requires the communications system to be synchronised, whereas generally speaking this is not the case with analogue systems.
Only digitised information can be transported through a noisy channel without degradationĭigital communications require greater bandwidth than analogue to transmit the same information. Definition of Digital – A method of storing, processing and transmitting information through the use of distinct electronic or optical pulses that represent the binary digits 0 and 1.
