He explains it very clearly, it reminds me on Razavi.

Really good set of lectures and excellent examples were taught on RF/Analog domain

Thank you very much for this wonderful content and clear explanations.

Once there is a noise, it depends on the response. Out of band noise can be filtered out straight in the RF/Analog domain. In band noise removal however is little difficult. However, using ANC adaptive algorithm in DSP domain can cancel it at the cost of some settling and training.

great lecture. thank you sir, thanks nptel

brilliant lectures..loved the way the Professor relates examples from wireless communications and RF

he made use of his tools perfectly in 2012 And now people say we aren't ready for online school Y'all aren't willing to Cause this is more than doable this is better than traditional

thanks so much , your lecture is very interesting , simple explanation , thanks so much

THANKYOU

Thanks 🙏🙏

What a great lecture! Thank you! Do you use any particular textbooks?

Hi Vincent, I am starting this course. Recommended textbook on the website is RFIC design by Behzad Razavi. I hope I am not too late.

@@nilanjandutta8799 which notes? You can take while watching the lecture. I don't have any notes.

Can we get video on filetr implementation, unit element , krudas identity, coupled filter, odd and even mode excitation, band pass filter section

There are really tough topics in rfcd to understand

it is 3 ps for 53:30

Can anyone please tell Which text book he is following/Which text book should i follow for this course?

what is the problem with high frequency while transmitting and after receiving? Sir, can you explain, please.

Real world data is usually low frequency. As an example, voice can be at max 20k Hz. This low frequency band is called baseband. However, now a days baseband is growing in size. Lets not talk about it now. Transmission of basebamd frequencies is not suitable for communication. So we translate the realworld baseband signal to high frequency signal (rf or rf band signal). Problems with high frequency/ rf frequency is 1) Real world data is not high frequency 2) Working in digital systems (which has several advantages) needs sampling. Sampling is easy in baseband. In summary: 1) Operating completely in baseband is a problem for wireless channels. It needs huge antennas and many other issues. 2) Operatting completely in RF is problem because of above mentioned 2 reasons. 3) So operate in baseband using digital systems and translation to RF for communication (transmission and reception) is the way to go.

May i know where is gsm radio architecture and cdma

Thank you Professor Shouribrata! :-) Your lectures are superb and very informative! The summary at the end is very helpful! Please direct me to where I may get the class notes, homework, and solutions? Your RF IC's lectures are what I needed to learn to get prepared for my job interviews, and hopefully work as Physical IC Layout Designer with RF IC's in USA... Take care, May you and your family be blessed! Your new and faithful student, Genevieve B.

The characteristics impedance value 50ohm... Where does this number comes from?? It could be more or less 50ohms?? It should match with Zrx and Ztx... Is there standard for impedance should be 50 ohms...?? I have heard many times but never get the proper justification... Can anyone please help??? Thanks

yes there is standards in design of tx line i.e 50ohms(less insertion loss and maximum power transfer ) and 75ohms (maximum power transfer)

How can I register for this a course please.

increase ur speed little bit bcoz ur teaching so slowly

You are right, I increased the speed of the video. It helps.

I disagree with your statement that the Tx and Rx would use a different LO. You actually want them to use the same LO.

@greywolf271

That depends on your transceiver application. If you're talking about a simplistic amateur radio transceiver, you could get away with using the same mixer LO for Rx and Tx. The lecturer is typically explaining split frequency operation for something like a mobile phone handheld device. Listen to the lecture again. It's not that hard to understand the difference

He is probably talking about the frequency bands that are used, like downlink has to be around 800 MHz while uplink has to be around 850 MHz (arbitrarily chosen values, not according to standards)
