Whats the X and Y Values that one can read from the Lock In?

Thanks much for the video, exactly what I've been searching. How'd you get so smart?

Can the Reference Signal be a DC signal when the signal to be measured is AC signal

This was fantastic explanation. I looked many videos for a simple explanation about lock-in amplification, but this one was really great. Thanks a lot

Very cool !!!!!

Thanks for the video. I am new to oscilloscopes. I have a Hantek DSO2c15 which sat on the shelf for more than 1 year. The ch1 and ch2 get 200-300mv noise on low voltage settings (20-100mv/div) when attached to only the bnc alligator probe. This is regardless of whether the earth and signal are joined. Is this normal? Is the alligator clip bnc probe acting a radio antenna or sis it a faulty oscilloscope?

How we can detemine the frequency of the signal? Would the fft function help ... ?

Thank you! Now, I've understood about IQ demodullation.

Great work, Mark. Not sure if you remember me, but we worked together when I was at Keithley instruments. I hope you are well

sir how to convert Z impedance real and imaginary and smith chart values

thanks

great explanation (and love your voice) thank you!

What I don't understand is additive and subtractive color mixing of those two would produce an amber color of light. So why not just use an amber light right in the middle of those two on the spectrum they would be perfectly balanced in their intensity and reflectivity. I haven't tried it myself but I'm just wondering because of the additive color blending of red and green produces yellow. So I'm wondering if a sodium vapor lamp being one of the purest yellow lights out there; would have any effect on blood. I question this because there's a couple of hunters out there that also agreed that warm LEDs are better for blood tracking than bright white LED. That would suggest that the yellow inside of the warm color LED is having an effect. You have better access to equipment than I do so would you mind testing these theories and maybe making a video about it?

Muito bom!!

Will this track cat blood after a dog attack on a cat if washed away and dried by the heat

Thank you for making the video.

This was an excellent description. Thank you!

can you please tell where can I get that ad630 module shown in your slide?

Fantastic!

Best lock-in detection explanation on KZbin. Many thanks!

great video, appreciate your work!

How come they are completely out of phase?

This was a great introductory video! Could you tell us something about how do RollOff and TimeConstants play a role in signal processing ? Thank you,

Why this reminds me to FT?

Great video! Thank you, Mark! :)

Thank you

Very useful info!! Thanks for sharing!

Interesting, thanks for sharing.

What a cool poor man's lock in amplifier. Mathematically, does this have something have to do with sine orthogonality while integrating them (in order to acquire the average)? Is that why the noise just went to zero when we multiplying it? And another question, if lock in amplifier's concept is this well known, what's so special about the really expensive lock in amplifiers out there?

Where can I buy it from?

Very Nice

Is there any good ref book for studying lock-in amplifiers?

You can also turn on bandwidth filter to eliminate a lot of the noise

thank you

I go the 100% cook over wood route, I have a BBQ with the side fire box, and smoke/cook them all day. But you have to like smoked meat, and some in my family complain that it's too smokey. Your lockin amp vid is how YT directed me here to your channel. I normally get the big slabs, and cut them in half. I've gotten to where I never salt or rub, as I don't want all the sodium, and they pretty much inject that into the ribs to keep the weight up for $. I've taken the facia off, or leave it on, does not seem to change the texture or chew factor. Nice detail diagram on the carcass.

Thanks for this video, just what I needed!

This is outstanding! The text makes your content easy and informative, and all your images support the narrative beautifully. Can we make this a viral challenge? #PostUpYourActivism #ShowUsYourPassion #HowIHelpMyCommunity. Oh, please can't we harness the power of clout chasers and use it for good? I really enjoyed the video, thanks for sharing.

Saved my life man

And since multiplying two signals at the same freq but at a 90 deg offset results in an average of zero, you would also multiply your signal with a copy of the reference but at 90 deg offset, and thus results in I and Q outputs

Great explanation. Very interesting concept

Very well explained

Great video, how could you know there is a 1khz sine wave in channel 1?

great explanation, thanks!

Hey I’m one of the kids that performed in that re-enactment I was on the union side and had the hat that barely fit me it’s super cool what your doing
