Electronic Filters - Vocademy 

Thanks Bob, Excellent video, really excellent.

Again a didactic masterpiece here, thanks Bob! Even after completing most of your Electronics Courses, did this piece increase my knowledge still some more. Great to see you going forward after all those setbacks! Wish you an ever increasing audience! Greetings from Switzerland! Charles

Glad you're back. Guess you weren't able to get things resolved with YT and Google. Shame. Hope you have better success this time around. Most likely be ok, but taking a risk of more issues. It's happened to others. Strongly suggest posting vids on other services for redundancy and to further expand your reach. YT is the biggest, but not the only one.

Wow nice video...Now I understand very well the functions of filters... Thank u so much sir, keep up the good job, godbless and more power

Good to see you are back Bob 🙏, and for a long time I was hoping you’ll do a video on audio filters/crossovers. Thanks again for lessons in electronics and hopefully the networking will start soon.

This is fantastic - the best explanation of this I've seen Thankyou

My favorite teacher is back.

Great to see you back!

The best teacher is back. Hope everything works out for you.

After all you have been through, it is nice to see you back again! 😂

Found you again you electronics monster! Keep on banging 'em!

the best teacher ever great information

thank you sir. this video helped me a lot.

Excellent as usual

Thank you very much for sharing your knowledge.

you are the king 👍🌹

Finally, you were missed! 👏👏👏

Hey good to see you back ,What is wrong with rsd academy ? You will continue here ?

Give Bob the Job!

Is there any way to watch the old videos? I had so many saved 😢

Thank you for all your efforts. ?can you make a auto cut off circuit for battery charging ? It would be very useful for us to understand how things work in relationship with other elements. Best regards Bob. Take care of yourself

Hey professor, nice to see you doing well! So is this the main channel now?

Very good video. Are you planning on showing how to know which filter to use depending on the application? Since there are several of each type how do you know the best one to use?

@ bob Duhamel please make such videos on integration of electronic devices, like RS485, Ethernet Networking. if you give us the introduction it will be far easy to understand further for US.huge respect from Pakistan

Great video. I wanted to start at the beginning to see your entire series, but your oldest video I can find is 11 mo's old. Did a lot of your earlier material get deleted?

Awesome 823

Hi in my country we have something close to OSHA Standards that regulate technical and formal preparations and safety rules according to working with electricity. Our system is TN-C. Many colleges of mine are confused (including me) with one particular rule that says when working on a power cable, you must securely disconnect phase wires and neutral wire and put grounding on all wires (phase and neutral) as close as possible where you are working. So the confusion comes from why we must disconnect neutral wire from ground in substation and then secure it by grounding it again but closer to work place. I guess maybe it is for safety if there is a fault or imbalance in the transformer in substation and voltage vectors and neutral point are displaced. Can you help me with that?

dear sir please how to get quasi sine wave (inductive crankshaft signal for automobile -12V to 12V ) from square wave i.e crankshaft signal (hall effect) varing from 0 to +5 VOLT using for exemple a low pass filter note: the frequency range is : 500 HZ TO 30KHZ THANKS SIR

"at DC capacitor is like open circuit" hows this possible cause in DC we get voltage across capacitor which is equal to the source voltage?

really good video
