Lecture - 10 Bandpass Signal Representation ( Part 1 )

[@noorfatimah848]

he is a prof. of iit and teaching communication.if he starting to show his talent u never able to get him........say thanx to him for teaching slowly......

[@mohitkhanna83]

The video is really helpful in understanding the need for low pass representation of a band pass signal and how to go about it. Great going IIT Bombay.!!

I tried to understand the concept of complex envelope in several documents but I found a lot of difficulties, I believe this video is very interesting. I advise you to watch the entire series.

I like this guy. His explanations are very clear. However, I think all lecturers on this topic need to spend a few minutes to really emphasise how these complex signals are constructed and used in practice. In particular, I think it should be emphasised that the real and imaginary components of the complex signal are both real... and they both really exist in our electronic circuits; we can measure them each with a real oscilloscope. We only treat the imaginary component as imaginary in the mathematics as a useful abstraction.

thx for clear explanation of how real passband signals and complex baseband signals are coupled together at transmitter and receiver side

[@adiviswanath]

Technically speaking the signals transmitted after up conversion and before downconversion are passband signals

Nice

[@linkmaster959]

I only wish he explained the difference between the message signal and sl(t)

[@rakeshreddy1365]

i think both are same

[@k.m.rveena9996]

Can anyone kindly explain how we got equationz at 31:27

[@Elfrania]

He skips alot if explanations too! Some audience may not be able to piece the concept together.

[@TheSohail02]

he is talking look like a news caster.......

I’m sorry this lecture made things worse and was very frustrating to comprehend.
