Thank you, great demonstration! I recently started teaching electronics technology to high school students in a career and technical school in the U.S. and I had just covered this very topic with a similar (but not as extensive) approach. I wish I would have seen your video beforehand, as you were able to elaborate so much more information and more concisely. I'll certainly be tuning in more often to expand my 'teaching tool kit.'

[briantamburelli]

Thanks. I needed more information before purchasing my first signal generator for my Electronics Laboratory Bench.

Thank you so much for the awesome lesson! It's pretty easy to understand yet important in the learning process. Grateful for your time putting this together.

[davedav]

This helped me understand a few things much better. Thank you.

[cthoadmin]

I love playing with lissajous figures with sig gens and an oscilloscope!

[td]

Thank you for expanding our thinking. Very interesting and useful information.

[oscardominguez]

Great video, great teacher, thank you

[emilcost]

Excellent demonstration! I like your style of teaching, and just subbed. I'm looking forward to looking at all your videos and the ones to come in the future. Appreciated!

For synthesiser low frequency oscillators at 0.001Hz and below are very useful control voltages for filters and such like (especially if you're doing ambient music). when you get that slow, period does make a lot more sense than frequency.

Good video although I suspect that if you have a sig gen you also have a DC power supply, but sometimes two sources are handy. I have been known to use the sig gen DC output with a negative offset to provide a -ve voltage for an op-amp.

[tgirard]

Brilliant mate. I always wonder what people use all the different wave types and frequencies for with a signal generator. 99 times out of 100 I'm simply driving a motor with pulse width input. If you have any other ideas I'd love to see him.

You really should use a non symmetrical waveform to test if a DMM is true RMS

[gilgil]

Do you have any information about modulation with this generator, or other similar equipment? Thank you.

Not correct measurment, 10Vpp = 3, 53Vrms because double Veff in sine wave, one Veff = Vp/square root 2
In you video must be 20Vpp to Vrms = 7, 07V
That generator basically generates the amplitude in Vp
In house outlet 230Vrms = 325Veff = 650Vpp

[JLinnooxs]

Can you post a link the distributor of Junctek signal generator i dont see it any where after a google search in USA thanks

[technishn]

The 10v Peak to Peak voltage from the Generator should be 3.53V RMS on your meter. The output from the generator must be putting out 20V P-P?

[jimyohe]

At about 4 minutes in you showed a formula to determine frequency not time yet you took the reciprocal of the frequency. The formula should show t = 1 / f .

[RensePosthumus]

just a question: does not each led needs its own current limiting resistor?

[gdj]

Who builds things, most just string together modules from flea ebay or back end express .
With no idea how the thing works or its rating !

Fail safes design, fuses & grounding are non-existent or a after thought .
( After being the operative world ) .
