Hi
Im all so new here but I have a bit of experience in electronics. I wonder how can I calculate the reduce of amplitude for a frecuency in a low pass-filter. And get the answer in degres (or per-cent). And what is it based on that "The resistor must be at least double the output resistance of whatever drives it for a reasonably low loss, and 10 times the output resistance for low loss. The resistor also must be about 1/10th the resistance of the circuit it feeds."

Thank you.

 

Greetings Saitam,

Like AAC, most forums prefer you to create your own thread rather than append your question to an active and possibly related thread. The benefits to this approach are two fold. Firstly, your question is more likely to get the specific attention needed to answer it and secondly it avoids an interruption in the flow of any on-going discussion that is taking place in the existing thread.

I see you have recently joined our forum. I hope you enjoy interacting with our members and that you obtain the information you are seeking.

I recommend that you visit our ebook covering Basic Electronics theory at www.allaboutcircuits.com if you have not already done so.

Have fun,

Ok, Thanx
I´ll know that when I next time post. But still waiting for that answer.

 

Take a look at the material covering series RC circuits in the AAC ebook.
