the main difference in analoge and digital system is analog is continues type of data and ditital is discreate type of data. e.g old galvanometer having needle is analog but new multimeter is digital in which voltage and current is shown in digits... analog is not much accurate..but digital is accurate...
There is no modulation of a Digital Circuit.Modulation is placing information onto an analog circuit to transport thatinformation to a distant location to be decoded/demodulated.Having said that, you can modulate a digital signal in dozens of ways,(Modem) and you can also modulate an analog signal dozens of ways(AM Radio Station, CB Radio, Walkie Talkie, FM Rock Station).NoteWhat this question may really be asking about is something like:"What are the differences between using an analog signal and a digital signal when you want to encode some information for transmission?"so that has now been posted as a separate question.
Digital Electronic is modern way of electronics technology it deals with logic function and operation (logical). It can only understand binary number system which is 0 or 1 . all the information which to be processed is converted to digital after that processing done. it has several advantages like- high speed, low noise , less error , low power consumption and high reliable.

Get a digital to analog converter box or connect it to a digital DVD or vcr.
They have their own merits and demerits you can't say digital electronics is best because in real world everything is available in analog quantity. Although Digital electronics is more reliable in comparison of analog because there is very high reliability in the sense (effect of noise) and correction of errors that occurred during transmission of digital signal, while this is not possible in analog communication.
Disadvantage of Analog Communication: 1)Analog Communication systems are costlier than digital communication system. 2)Less Security in Analog Communication 3)More prone to noise interference.
Because I am an analog creature living in an analog world. If I were a computer I would use digital communication. :-/ ?

Some common important topics in PUC 2 Electronics might include digital electronics, analog electronics, microcontrollers, communication systems, and electromagnetic theory. It's crucial to understand basic concepts, circuit analysis, and applications of these topics to excel in your exams. Practice solving previous year question papers and focus on understanding the fundamental theories behind these concepts.
Analog communication considers infinite amplitude levels. But in digital communication only 2 levels of signal is present.
In electronics engg we study abt the behavior and effects of electrons to develop components, equipments or systems such as electron tubes, ic, transistors,pcb etc.. In communication portion we can study the different communication systems in detail....
Yes.
With analog and digital signals.
Power electronics is study about controlling the power using electronics devices, Electronics is study about controlling the electrons flow&make amplification of electrons for required areas
The two types of communication channel are analog and digital communication channel. An analog channel uses continuously varying (analog) electrical signals while a digital one uses discrete signals.
