I'm a PhD student with one of my feet in communication. Your video series cleared up a lot of confusions I've been holding in my mind for a long time. Thank you dear sir. The community needs more great people like you.

[plemplem]

I do have my master‘s thesis defense tomorrow, your video really me in understanding the basics that may come as questions. Your video(s) helped me so much. Thank you very much an continue the great work, you really inspire !

[김지원-nvq]

This video really helped me understanding these confusing concepts! Thank you so much :)

[zahraazaidan]

I really don't have words to thank you... you made it more than clear

I had 3 subjects about communications in college and we were always talking about this, never understood, just learned the formulas and got straight As. Now that I am writing my diploma, I wanted to know about this, bcs I one section I write about it. This video helped me sooo much!! Thank you very much Sir!

I have listened to multiple videos to refresh my mind about communication. This channel was the best which answered many of my doubts. Thank you!

[abutaubah]

A very good explanation. Much appreciated 👌

Mr Ian, you're an invaluable resource to the engineering community.

This is an awesome video for seeing HOW data rate and bandwidth are related, but could you also do a video about WHY data rate and bandwidth are related? Something I'm trying to wrap my head around is WHY does increasing data rate need more physical space in the RF spectrum to accommodate that increased data rate? What is it about using more RF spectrum that allows more data? The way I think about it in my head is it's like parallel computing where by adding more wires (or frequencies) in a cable (bandwidth) allows you to simultaneously send more bits, and therefore achieve higher throughput. I'm sure this isn't actually why you need more RF spectrum for a higher data rate, but I think it helps explain what I'm trying to ask. Thanks for the video!

OMG thank you sir! extremely helpful!!!

[yutunchao]

This video is very helpful! Many thanks for such excellent explanation!

im a telecom student from Ukraine. Thank you a lot for a super clear explanation!

[sayyidrajab]

Really good video! Clear and informative.

[soaiem]

Thank you so much, i was so confused.

I continue to watch your videos because I always gain some knowledge from each. I really do appreciate them!

The one question I had is that for any given amount of spectrum bandwidth, how do you calculate the symbol rate?

For example, say you have 20 MHz of spectrum in 2.4 GHz. How do you figure out the symbol rate?

On a similar note, if you have the same 20 MHz of spectrum, but it's in the 60 GHz range, does the alter the symbol rate or is it still, ultimately, the same?

A concise and broad explanation, that can be used as orientation to dive deeper in the corresponding topics (Interference, filtering, modulation, ...). Thank you so much!

Professor, The problem you discussed at @5:46.

Every practical signal is time limited and signal don't exist on t < 0. in that case why do we need to worry if signal starts infinite time ago. My understanding is signal being infinite is just theoretical concept. please correct me

[JaySmith]

I have confusion about bandwidth and capacity. I see often they're used interchangeably by people. Are these two accepted uses for 'bandwidth'?
1. The maximum possible data rate for a channel.
2. The frequency range which can be sent over a channel.
To me, a bandwidth is a frequency range, and expressed in Hz, but without more information e.g. on the symbol size, and how much is actually available for useful data it says little about the channel capacity or data rate. To me, channel capacity is the maximum possible gross data rate that could be pushed over a channel; Am I wrong?

Amazing explanation!
