Very well explained. This is how we need to approach every topic where “WHY” should be answered before “HOW”.

@friosminsysnym 2 года назад

I’ve been watching several videos and none of them explains the motivations of implementing PLL like you do! This is explanatory!!!

@hamza7595 3 месяца назад

Finally, someone answered the most fundamental question. Thanks alot

@tolgahannsusur2534 6 лет назад

Please keep going, it is the best RF training ever!

@CoversTavo 2 года назад

Thanks dude. My professor is so bad explaining, now I understand the concept!

@theclerk3163 Месяц назад

5:00 Hit my question right on the head. I appreciate this video so much

@nguyenanhdanh5286 5 лет назад

Thanks sir.! The best and most perspicuous explanation of PLL I have ever seen. Keep going.

@TheMrKarica 6 лет назад

OMG man now I understand this tool. After a Thousand vídeo . Thank you.

@WoWPro71 4 года назад

I finished my practical engineering studies 3 years ago and i had how clue how this cuircet works until now. Thank you so much)))

@agstechnicalsupport 5 лет назад

Very very good ! Clarifies the basics of phase locked loop (PLL) concept.

@Rami7605 6 лет назад

Very good explanation. Simple, straight to the point and even answers my question. Will bookmark it for future reference.

@pepesworld2995 4 года назад

not if i bookmark it first!!!

@MikeOxolong Год назад

Thoroughly explained! I watched 3 videos and asked chat GPT and didn't understand why we use PLL, when we have crystal clocks and power amplifiers.

@bendresachin8454 2 года назад

Excellent video for PLL, Before watching this video I have many doubts ! Thankyou 🙏

@denzelkapoor2475 5 лет назад

This video is just what I needed! Answered the most basic question that other videos didn't

@pepesworld2995 4 года назад

yeah mate. its actually a bit of a bastard to teach. i did a whole course on digital communications it at university and phase-sync was completely omitted. not even mentioned in the material. taught QaM, but no phase locking. figure that one out. i honestly ran into the trouble of trying to make a demodulator and realized i was missing something. and found PLL on my own.

@2TAK322 2 года назад

Aksandan anlayıp Türkçe yazıyorum :-) Çok güzel anlatmışın hocam. Eline ağzına sağlık. Çok teşekkürler.

@sprytnychomik 6 лет назад

Great video! Not only it explains how it works (like any other video on the subject), but also *WHY* even bother with PLL in the first place.

@blackeyedraven6282 3 года назад

Thank you, this tutorial is amazing.

@aksharasajeev9746 4 года назад

Thanks a lot sir

@jimzweighaft8079 8 месяцев назад

Thank you for answering an important question that is overlooked many other videos: why can't we just use the VCO or the reference oscillator itself without the feedback loop.

@nikolajapostolovski 6 лет назад

@advanceddesignsystemadsrfi449 4 года назад

5:12 this question bothered me a lot ,,,, but i satisfied with Frequency sythersizer

@arvinbaba 3 года назад

Thanks, where are you from?

@rajbakhunchhe4254 5 лет назад

If two frequencies are different, then the phase difference will not be same and input voltage to VCO will not remain constant. How will this control the output frequency?

@zainabashai7546 Год назад

What is the threshold frequency below which all frequencies are considered low in RF design and above which all frequencies are considered high in RF design?

@shivac3 5 лет назад

Tnks man

@skyking6989 4 года назад

So essentially it is a reference point and it forces it back into lock if it drifts off frequency?

@chiraag3972 4 года назад

Great explanation, thank you. One question - how are we increasing the frequency of the VCO if we are constantly trying to match the phase difference of VCO and the reference oscillator?

@Mangakan_desu 4 года назад

through the divider.

@VikramBamel 2 года назад

VCO is typically programmable and uses frequency multipliers to achieve higher frequency. At a given voltage, say V1, the multiplier would be set at a programmed value, say 10X.

@VikramBamel 2 года назад

Also, once we set the VCO to a desired frequency(by fixing the multiplier), there’s no need to keep increasing the frequency any further. We just need to maintain that high frequency as good as we can.

@zainabashai7546 Год назад

Why do we have an Amplifier before the Loop Filter? Is it because without the amplifier, the average DC voltage produced by the Loop Filter will be lower than needed? Will VCO will receive lower DC control voltage than needed due to the nature of averaging?

@farhanshams3994 5 лет назад

Why we use low pass filter in it plz??

@esada.811 5 лет назад

nice video and nice Turkish accent :)

@hrh2092 3 года назад

He is not dorkish, he is iranian but he made a mess of this "course" anyway.

@altuber99_athlete Год назад

Interesting. So a phase detector doesn’t only detect that two signals are in phase, but also that they have the same frequency. • Equal frequency and equal phase angle: constant zero phase difference. • Equal frequency but different angle: non-zero but constant phase difference. • Different frequency: time-varying phase difference.

@bonbonpony 3 года назад

Yeah, but how to build a frequency divider that could work with gigahertz frequencies? :q Usual CMOS counters don't quite work with such high frequencies :/

@zainabashai7546 Год назад

Why don't we just use the reference oscillator to provide stable input signal? How is the reference oscillator not prone to temperature and noise effects?

@zainabashai7546 Год назад

I realize that you answered my question in the video. Great!

@advanceddesignsystemadsrfi449 4 года назад

what if Phase difference =0 --> DC voltage at VCO=0; then How o/p frequency is obtained? please answer to this question
