15:55 How comparator differentiate in between a/2 because amplitude is same

[@ghassensaidi8609]

that was also my question. After thinking a long time about it this is what I suggest: in a certain time period T_b, if a 1 is sent then the comparator gets A/2 from the top side and nothing or maybe 0V from the bottom side --> it gets recognized as a 1. Now if a 0 is sent then the comparator gets A/2 from the bottom side and nothing or maybe 0V from the top side --> it gets recognized as a 0

[@ch.mratnakar3688]

The output digital signal might be in the form of Polar NRZ. Bit 1 is represented by +A/2 and bit 0 is represented by -A/2.

Thank u Vaishali for great explaination...a small feedback pls explain with writing notes so that we can note it down which will help in quick revision during exams.

[@spokenenglishmentsbd9998]

Lots of love from Bangladesh, Mam. U r so good looking.

[@chandrug437]

Awesome madam.. very informative

[@hafizurrohman9731]

Thank you so much MISS... for your great explain

[@sonyk4429]

Mam please reply me this discussion of fsk is same for basketball means binary frequency shift keying.... Tell me once

[@sonyk4429]

Not basketball it's bfsk

[@shyamgudikandula3877]

Mam why do we use inverter in the transmitter circuit

[@Sars.K]

How does that root 2 p in the starting came for the message signal I don't get it you didn't explain that thing.

Thanks ma'm 🥰🥰🥰

Kya m isko bfsk me likh skti hun mam plz ans

[@Kashmiri.111]

3:49 girls and maths 🤧. √2ps or √ps2 is one of the same thing

[@harshitacharya5711]

Thank you

[@allahakbar3958]

why those signals are right angles to each other

[@ashirwad_joshi]

Brilliant

[@manishatiwari8400]

A/2 is not frequency component, it is only a constant, what u explained same i explained in my ppt but marks was detected because of that A/2, i explained A/2 as low freq which is wrong

[@justadreamerforgood69]

Constant=DC component=0 frequency~low frequency

[@negisamsumit0]

so cute'

[@VaishaliKikan]

Thanks for your feedback and for connecting.. I hope you will stay connected for upcoming videos

[@raht9578]

padle tharki

[@milantie1072]

what is Ps?

[@Rocks740]

Madam...at the end of Lecture. Mathematical analysis is not clear

[@raht9578]

ghanta clear hai kuch

[@vikrantgupta2459]

I think your bandwidth calculation is not write it should be fh-fl+2fb not 4fb.

[@VaishaliKikan]

I am talking about the bandwidth occupied by the desired signal.. In between bandwidth is not used .. 2fb for upper band and 2fb for lower.. Thank you so much for your valuable feedback.. Stay connected for upcoming videos..
