Passive RC high pass filter tutorial!

A tutorial on passive RC high pass filters. You can use them to filter out low frequency signals, or remove DC offsets from a signal.

That moment where you are in college and you need to come to youtube in order to understand what your teacher couldn't get you to understand... Thank you!!!

If my electronics professors explained like you, my following exam would be a piece of cake.

Thank you soooo much :)

OMG. 11y and still one of the best tutorials. I have no clue why I stopped subscribieng this channel. Thanks man for your work!

[darrencady]

That was explained perfectly. You said everything anyone needs to know and nothing they don't. Well done to a great teacher.

This is much GREAT information in this compact video. I love how you provide your motivation to make choices in circuit design. You could spend hours scouring for all of this information in different places. THANK YOU.

[meta_ai]

you taught me what 3 books failed to teach. thank you. at last some sense to the madness. every book just assumes a bunch of stuff that isn't clear at first. made me day. why dont you have more subscribers.

This is wonderful! The break down of each part of the circuit and its purpose is so incredibly helpful. Thank you afroman! Plz don't stop.

Love the Afrotechmods channel! I am glad this popped up, I once again got lost in the billions and zillions of other channels. This is a nice basic video, nice production quality and very well explained!! My trip back to the basics, I also adore the W2ae3w channel, you guys are both talented and entertaining!

[TheCrazyStudent]

These videos are great!! The way everything is being explained makes it easy to understand. Please continue making these awesome videos.

Dude, your two videos on Passive High Pass and Low Pass filters explained the basics to me perfectly.
For the past week I've been trying to get my head round the concept but all the information I came across was all Pseudo Babble and Techno Jargon, well above my head. This was perfectly explained and now I understand. I've even memorised the formula too! LOL. I'm working on a project at the moment which involves RF and Audio and I'm getting a distinct hum on the audio line from some sort of RF interference which I'm working to track down and eliminate. If I can't find it to eliminate it at source, I am going to cheat and filter it out of the audio line using a high pass filter with a cut off of about 250Hz so it's a gradual decline around the problematic frequency range. Thanks again!

One of the best explanations of all time

[jbflores]

WOW! that's the best clear explanation of these filters iv'e seen or read! thanks!

[brownmonkeybananayellow]

Great videos. They're so clear! I wonder if you do video narration professionally.

I do have a novice question though. I just watched this and the low pass filter video but I don't really understand what you mean by avoiding overloading the microphone with a high resistance.

Best speech ever of an Oscilloscope:   "Shut up you got me for free!" 
Great explanation of filters. Thanks a lot

hi. when you mentioned that the voltage across capacitor cannot instantaneously change because it needs time to chagre and then followed by saying if a sudden fast change voltage is pumped to the caps input it will instantaneously appear at the output side. i am confused by this statement.

[BeatRatio]

Great video! Very clear and well explained :) I'm thinking of building a simple HPF for music recording. Had a look at my mixer manual and it says something like:
Source Impedance: 10K ohms or less
Input impedance: 100K ohms
Does that mean that the resistance I choose for the filter should be 10K or less?
Cheers

Fantastic videos.The best here.Definately.I would like to understand how you come up with a 20 mv p to p with the 9v and the 5000ohm resistor and what exactly constitutes a DC Bias and how is it made in a circuit.Cheers.

[playingidiot]

3:34, finally I know why ecg's do that weird pattern when the leads are not connected.

[VictorRivarola]

You did an excellent job in explaining what a high pass filter does. Thank you.

Now, that leaves me up with one question unrelated to high pass filters but related to your example, why are you using a high pass filter to remove the 9V DC signal, right after you've added it?

[psyolent.]

i had to LOL at the 'shutup you got me for free'. thanks for the explanation
