Hello sir thank you very much for your valuable effort . these are very useful video..
Sir we want on
BFSK
DEPSK
QASK
M ARY FSK system
It was a nice lecture. Thank you sir.
Very very very very happy thank you so much
Your welcome
Sir it's very helpful .. please mention the reference books for this course
Super explanation
Love and happiness of students is my ultimate goal, God bless you 🙏, keep learning and keep progressing.

sir jo last topic tha ASK . uska defination me hai ki wo digital to analog convert krta hai...pr jab aapne demodulation technique btaya usme at the end to hme m(t) massage signle hi mil gya jo ki digital hi hai to fir kaise ye digital to analog convert hua. please reply
fc1 > fc0
Sir, fc1 should be greater than fc0
The waveforms are showing opposite
your right. makes sense @ 4:30 it should be a lower freq for fc 0
Are Fc0 and Fc1 carrier frequencies?
thank you sir

Sir in FSK were are using two carrier frequencies?
For 0 we using carrier frequency fc0 and for 1..We using carrier frequency fc1??
It's nice of lecture, thank you sir. I want to watch any video of your channel

Is this FSK modulation and de modulation is same as BFSK...??

Is Fc0 and Fc1 frequencies of carrier signal?
Thank you very much
sir please review this videos at 18:14 for minimum b.w =Lr
Sir at 19:36 your explain modulation circuit for fsk but in circuit you used m0(t) and m1(t) but we give one message signal and two different frequencies cerrer signal
I thik here you do mistake you must write m0(t) at both side
Am i right ?
good. Thank you sir.
Your positive comments motivates me.
sir if you don't mind your voice should be a bit of audible sir.otherwise, it's a great session sir
It will be good in future videos
Thanks for the suggestions

Sir!!What is the work of interlever!!!???
Ur video is very useful and wonderful sir but ...
its frequency shift keying and every time u say binary phase shift keying
Binary face shift key or binary freq shift keying
sir how are u diffententiating between bfsk nd fsk
bfsk is only binary fsk
Sir in our syllabus there are topics named as BFSK and BPSK so are they same as FSK and PSK ?
BFSK is binary FSK and BPSK is binary PSK.
Sir edhi memu 7marks ki rayacha
Ma clg lo derivations pettaru ... Chala lengthyy ga unnaye avi..
Very helpful!
@15:57 says 'for BFSK Binary Phase Shift Keying'...what is the new term 'Fhase' you have introduced?
Sir, why gaping between two band f0 and f1 is 2∆f, why not ∆f?
It is just notation.
In most of other materials that I found the minimaum BW of FSK stated as 3R (R=Bit Rate). But in this video it is stated as 2r. I have tried in so many ways to relate these two equations but faild and now I'am super confused. Can anyone clarify this issue?
It is frequency of message signal or amllitude of message signal
Hi, I am new here. Can someone points where this (1+d)r comes from?
What is d?
1+d is the Proportionality Constant!!!
@@rifatbhuiyan9343 d = Factor for Modulating and Filtering Process !!!
14:04 Sir, how we have taken L=2
Thank you Prof. Please suggest a textbook for the subject.
Many .... sorry but can't remembered the names of those.
You can refer, "Signals and System" by Tarun Kumar Rawat
@@shivamxsingla Thank you for the update
Sir its varies with frequency or amp?
sir can we get these notes which you are making
if anyone made please reply
where can i get your this hand written study material
Go through my android application engineering funda where you will get all materials, i have remodified it.
@@EngineeringFunda Notes of digital communication are not available on engineering funda application
Hello Sir, can we produce an FSk signal with 2 ASK signals ? My teacher says no :(
If you have two different Frequency signals then only you can form FSK
ua-cam.com/video/AGVtHqMTd-Y/v-deo.html
While using single frequency say fc0, why we use band around fc0 for calculation???
Single frequency is not possible to use in any circuit.
@@EngineeringFunda So, can i understand it like, the spread of single frequency into band is because of circuit properties, not the inherent design of the system. Good circuit ---> Narrower the band... Bad circuit ---> Broader the band? Is my understanding correct??
What is the part of the panel that can do the frequency shift?
Tuning. Resonation. Sequential.
How did you manage to get a camera at that position
Using stand
Please decrease the number of advertisements between the lecture sir
Fc1 and fc0 ..hoping fc1 is greater than fc0..but it is showing fc0 is greater.. please correct it..
I dont think equation phi FSK= m0(t)*cos(wc0t)+ m1(t)cos(wc1t) is correct
isnt that m0(t) always equals to 0 and we only have m1(t)cos(wc1t)?
Oh nvm...
It is perfectly fine
Here what is d
OLLARER OLLARE OLLARE OLLARE
13:05 will BPSK have the same BW?
Sir what does d and r represents in band width
D denotes Proportionality constant and r represents baud rate
What's FSK detecto?
How is the gap "2 delta f"??
2 freq assign for each bit, so why 8 freq for n=3 bit? supposedly, 6 freq?
It starts from 000 to 111 so total 8 frequencies
what will be max BW of FSK
Plz upload msk transmitter n receiver
what are f0 and f1
FSK coherent demodulator r FSK coherent receiver ki same
At receiver we have demodulator
So reciver ans demodulator is same
Sir minimum bw = 2(Rb+@fm) kno use kore
Sir please provide a notes for the lectures
Sir,where we use these ask and fsk? At transmitter or receive r?
At Transmission, there will be modulation and receiver there will be demodulation
Engineering Funda but you are saying ask,fsk are used to convert digital to analogue. Is this happen in transmitter?
Yes its digital modulation Schemes
Sir, be careful while speaking, you're continuously saying BPSK from 16:00. Its confusing.
Sorry for that, actually I have made it at late night and that was happening with me.
is fc0 always bigger than fc1?
try to give less ads.
Sir what is bod rate
Its boud rate. It is symbol/sec.
I have made separate session on bit rate and boud rate.
is there any derivation for BW=(1+d)r??
It is very complex, i think this is sufficient for you.
@@EngineeringFunda thnx a lot !!! but will u plz give me a refrence regarding that??
Hykins and sanjay sharma can help you. But for that it needs good understanding to understand that.
and again what is denoted by r here?? may be by any chance I am missing it..
@@tamimshikto1710 : it is boud rate.
at 14:01 speaker says 'for bPsk' then writes bFsk.
why it is L-1???? why it is not only L???? any logic behind this.......
Any sequence starts with 0. Then you will observe that total sequence L = 0, 1, 2, ..... , L-1
@@EngineeringFunda OK understood....thank you so much......
Can anyone hear cricket in background
Hello. Thanks for your Videos. Do you have online (skype, viber) training for Wi-Fi ? If so how can i contact ? Thanks
wtf is d in that bw formula!
Please take care while pronouncing BFSK you told it as BPSK..👍
sir Wc0 and Wc1 are high frequency!!
so better to use BPF compare to LPF!!!
cill down buddy no need for so many exclamation points lol
itna ads mt lgao ..koi padh nhi payega
How will he earn then?
