This man (Captain T.Rainer) has really helped me "get it". And I'm not talking about the 'skirt kind'.. What a wonderful gift to humanity.. really, for all time (until we are hit by a huge meteor or something). Very COoL. Thank you for the video P.R.O. SUBBED! Da! p.s. Thank you for the Twilight Zone™ 🔉 blast from the past
I did all this stuff as a technician in the army 50 years ago - such very nice, kind and supportive people l worked with compared to many of the civilian places l worked afterwards.
I love old instructables like this, and I strongly recommend it to anyone that wants to learn about electronics, these materials explains it in a simplest way, making very easy to understand, a characteristic hard to find in nowadays articles, that presume that you already knows the basic principles...
Very resourceful. These days basic electronics is never taught in classes properly, as things have become very advanced and lot of chapters need to be covered in small time. But during those days, when this video was made, LC filters were probably quite advanced and hence covered in details. I especially like the explanation for T and PI section filters.
I am not sure if it was advance staff at that time as they are just basics but I appreciate good explanations maybe because it was for Army purpose so they wanted to be as simple as it can be? Still one of the best explanations about filters. Another thing , I have acces to free courses (from my company where I work) and they have similar courses (but modern courses!) for filters and it is very good so if they want they can teach but somehow these days people have no motivation or money or I don't know what to teach properly...
Electric circuits, like filters, where he said at time 1:20, "all filters consist of capacitors, inductors, and resistors" -- reminds of Taco Bell. They sell the same few ingredients, just in different combinations
In part A, as well as this video, they say that the resistor has no filter action, but in reality, the resistor has both a slight amount of inductance, and capacitance, and would become apparant at the higher frequencies. Everything has some L and C in any AC circuit, and must be considered as stray L and C.
That's not really true. You don't have to worry about any of that in normal circuits any more than you have to worry about the "reactance" of the wires. If you are in the middle of an integrated circuit "chip" where you are running at super-high frequencies with square wave components you need to take this stuff into considering, otherwise it's like claiming you have to worry about relativistic effects when you walk to the park.
Why don't I ever get around to making a notch filter for my guitar amp! That freakin' hum at 60Hz and probably 120... bugs me. Humbuckers are too boxy sounding. Maybe I just figure that Fender, or Marshal, or whoever would've already made it.

Not Army, Air Force training video! Thanks for sharing this; I remember learning this stuff years ago.
clear and precise, thank you so much

thank u keep it up please
They didn't waste time, back than.
Where is next video?
In part A, as well as this video, they say that the resistor has no filter action, but in reality, the resistor has both a slight amount of inductance, and capacitance, and would become apparant at the higher frequencies. Everything has some L and C in any AC circuit, and must be considered as stray L and C.
Whats this circuit for?
Band pass filter circuits are used in radio tuners. And other applications where you would need to hold on a specific frequency.
I didn't know Bill Clinton was a US Air Force Electronics Technology Instructor.

Go look inside arena speakers and power systems..
There's a really annoying white noise
funny considering the subject matter
