[@ecerahuljain]

Thank you for this video

[@nikhilKumar-ui8bs]

Sir at 5:30 why u did phase reversal 0 to 1 u told we will take phase = 0 when 1 will be msg signal.

[@bijunilan5245]

sir, can u explain why the non-coherent demodulation is not possible in PSK?

[@bijunilan5245]

@Ahmed Cole why are you saying this?

[@quasar7312]

What is r in the formula for bandwidth? at 6:08

[@nikhilshrivastava5459]

baud rate

[@RahulSaini-jf4sz]

qpsk pr b video bnao

[@EngineeringFunda]

I will make it after 2days

[@shahedsolutionpoint6659]

sir i don't understood the phase reversal in psk

[@vijaynavale3919]

Sir but you said this techniques are digital to analog and at demodulation you took output in the form of1010 ???

[@vinaykushwaha5223]

you are modulating a digital signal with analog carrier. your message is digital so demodulated output is also digital.

[@jokergaming2073]

4:10 I think that there is a mistake in the phase reversal..........btw thanks

[@ahmedjamil880]

No, in fact, I was also imagining that there was a mistake in the part that you referred to, but after checking, I think that the virtuous doctor meant that the output signal will be the same phase as the carrier signal when the information signal is one, but the output signal will be the opposite of the phase of the carrier signal when the information signal is zero. the inverse will take place at each up and down edge of the input signal

[@subhrajitnandy1685]

Modulation and demodulation part was little bit complex then usual.

[@moulibendalam3965]

Please provide theory or notice also

[@rohankrishna9499]

what is d and r in the bandwidth

[@pujithakaricheti8170]

r=baud rate,R=bit rate,n=no.of bits

Why non coherent detection is not possible in phase shift keying?

[@rd1abrar924]

Same question here

[@priyadarsinibehera2599]

Sir how 90 is represented as 01 qnd 180 as 10 and so on...

[@entropiclips]

we have just given the four phase a digital representation of 2 bits

[@aakashSky-0]

Band width = (1+d)r what is r here?

[@jimmoriarty5993]

baud rate

[@ABHI-yf4hz]

Is ur psk wave form fir First bit is similar to carrier signal

[@ramsurya6668]

I have a doubt sir , During modulation the binary input is multiplied by carrier signal so when there is zero's in message signal then multiplication of carrier and message signal during modulation is zero then how changing of phase is happened

[@EngineeringFunda]

That's what explained in video

[@dookiedoo2]

why effect of noise is less in psk compared to fsk

[@raenashaikh3377]

Because noise affects the strength (amplitude) of the signal. So even if the amplitude has changed due to noise the detector at the receiver's end will be looking for the phase changes in the signal to get the data.

[@soumikdutta77]

Hello sir in FSk and PSK how L=2n???? In multilevel because yo havnt told what is L here and how l=2n?

[@Aryan-ji2nk]

Sir If a question comes to for generation and detection of psk , then can we use the same block diagram and explanation as you taught in the video or not?

[@aaravgavshinde]

have same question, tomorrow is my exam kindly reply if you got answer

Can we make a same graph for qpsk ?

[@EngineeringFunda]

I will make saperate video on qpsk

[@joyfuljo7788]

Sir is it psk and bpsk are same

[@EngineeringFunda]

bpsk is one of the form of psk. BPSK means binary phase shift keying, where there are two phases, one phase is for 0s and another phase is for 1s.

Why u always taking carrier signal as coswct ?? Why not taking sinwct?

[@EngineeringFunda]

No issues if you take sine or cosine.

[@twinkle176]

[@balajibaheti8577]

is it necessary that we have to change phase by 180 at 0 and 0 at 1?????

[@EngineeringFunda]

Nope not nessesary

[@luckypavan7869]

Avoid back ground noises

[@karankedia1413]

hello sir, could you please include the PSD of all the modulations also? that is also one of the most frequently asked questions in the exams

[@sameerbilla515]

Sir multi level bandwidth formula?

[@ashmitabanerjee]

PSK signal is incorrect. Phase should be inverted in 0 to 1

[@jadhavbaburao5104]

Babruao. Jadhav

[@jayparekh7598]

Kept signal as it is in 1 and change the signal 180 degree in 0 thats the right way to do it

[@balajibaheti8577]

again i think there is a mistake in shift angle in Qpsk!!! it should be 00-45 01-135 10-225 11-315

[@EngineeringFunda]

It is correct here. So don't worry about it

[@himanshuful]

4:48 The last Phase reversal is incorrect. The carrier waveforms must be integral multiple of 1/Tc, in last one it is not
