I just realized I have been binge-watching Sunny's playlist even though I don't have an exam tomorrow. It's amazing to see how passionate he is about this. YOU ARE THE BEST.
1) Baseband is related to digital signal transmission where the entire bandwidth of a baseband system carries only one data signal at a time. In other words, every single signal would require an exclusive use of the shared medium. When I use the medium, no one else could be able to use it. They must wait their turns. Ethernet is an example of the baseband system. Regardless of different versions, whether they are early Ethernet, fast Ethernet, or 10 Gigabit Ethernet, they all contain the word “Base”. They are baseband. 2) Baseband also refers to the original frequency range of an analog signal before it is modulate to a different frequency range. An audio signal may have a baseband range from 20 to 20,000 hertz. When it is transmitted on a radio frequency (FR), it is modulated to a much higher frequency range. AM and FM are two comma modulated technologies in radio broadcasting. Now let us talk about broadband. The term “broadband” technically refers to any type of signal transmission technique that carries two or more different types of data in separate channels. Broadband signals can share one medium. It is like a multiple-lane highway. Two or three vehicles can share the highway side by side at the same time. Broadband is also used as a marketing term for Internet access. This meaning is only distantly related to its original technical meaning. In popular usage, broadband Internet refers to any high-speed internet connection, such as DSL, cellular, cable modem, or satellite. However, Broadband definition differs from country to country. In North Korea, the broadband may not be qualified as the broadband in USA. In summary basement is related to digital signals while broadband is related to analog signals. Baseband system does not allow digital signals to share one medium simultaneously while broadband system can transmit different data side by side at the same time. For analog signals frequency division multiplexing or OFDM. it used to make analog signals share one common media for digital signals in a baseband system. time division multiplexing or TDM it used to chance me the different uses data over one common media .TDM divides time into slots or intervals and assign .them equally to these users in this way everyone has an equal share in general baseband system is a transmiting less amount the data than our broadband system .
Sunny, thank you sir. You have an amazing gift of breaking down complex concepts into something many people can understand. Thank you for helping so many of us!
this video is awesome, thank you. and just to add something, you can see the word "base" in some ieee standards for ethernet, e.g. in 100basetx the 100 means 100 mbps (actually it really means the frequency), base means baseband and T refers to the media (twisted pair cable)
sunny you are my best instructor and I hope you make a videos about routing protocols and STP ( spanning tree protocols ) in separated videos with every protocol. And thanks for your hard work on illustration. Regards from Egypt
I have a question, why does ISDN is not a broadband system if there is a multiplexing technique involved? I'm asking this because in your ISDN explanation you refer to ISDN as a non-broadband transmission at the end of your video. I have this confusion, somebody please help me. Thanks you for your atention and may Chirst bless you!
Very good explaination, but I have a question for future calculation. If I have a 1MBit/s TDM with 24 timeslots for example, I would divide my 1MBit/s by 24. But what do I calculate when giving the same amount of data per second on FDM?
If we are using baseband e.g ethernet for internet access then why we are saying broadband internet for accessing internet? Confused 🤷♀️ And is it baseband we are using to access internet from ISP ?
