Wow! There's even a wrong explanation to a wrong conclusion!moamps said:Excellent?
I have ignored this so far...Phrazemaster said:Gosh...now what I understood is all in question...sigh.
Sorry for posting this. Mods, you can take this down if all it’s doing is spreading misinformation. Cause not being an EE, I really thought this was a good article.

Ps maybe it would be instructive for the geniuses here to explain what’s wrong with this for clarity...
I think it would be worthwhile explaining the faults. Maybe they'll read our comments and fix it (or just take it down I suppose). But we need to provide concrete examples. So ...moamps said:Excellent?
Impedance & Frequency Response
The output impedance of a device and the capacitance of its connecting cable form a simple first-order low-pass filter, producing a 6dB/octave attenuation above a certain frequency. However, you need either quite a low output impedance or quite a long high-capacitance cable to bring the turnover of this filter into the audio band.

Sorry for confusion I spread. I thought I was learning something. All I learned is I don’t know anything.
Thx

It’s a great idea.CJ said:offering up alternate articles would turn around the situation and help others to further their knowledge along the lines of AC signal theory at this juncture of universal understanding of the universe, can i say that legally?

Thanks Moamps and Winston O.moamps said:That's not your fault. This article is there more than 15 years. That's the problem.
I am still not in any hurry to read it, but the laws of physics have not changed in the last 15 years...moamps said:That's not your fault. This article is there more than 15 years. That's the problem.
squarewave said:1) 600 ohms out Z into 600 ohms in Z yields a 6dB drop but for some reason the author uses a weird unrelated example of loading 600 ohms with two 600 ohms in parallel. That would NOT yield a 6dB drop. 600 ohms into 300 ohms is a 9.6dB drop.

I think it's too late for that as forum members have started adding useful content.Phrazemaster said:Ok I’m asking - mods please just delete this whole thread.
