Re: Electronics 101010010010

"...start juggling various levels of inductance and capacitance around while looking at bandwidth, conductivity and power transfer."

Conductivity does not change with frequency as it is a function of static resistivity, conductor cross sectional area, and length of the conductor. Perhaps you meant conductance. Or maybe admittance.

"In order to achieve desirable levels of specific electrical attributes, one may have to play with certain conductor geometries, possibly even multiple different geometries in the same cabling."

Define: "desirable levels of specific electrical attributes" (Or perhaps just name the electrical attributes, and explain what a "desireable level" for each would be.)

So basically, if I am to understand your very detailed approach to AC cable design, if one "juggles" RLC values and "plays" with multiple geometries, he can lower "excessively high" series inductance from somewhere in the order of a few pH/ft to ?????? (some unmeasureable value?) and create traps to block "certain" radio frequencies by some "desireable" amount.

WOW! So far we're doing a whole lot of juggling and playing, but you're still nowhere near a definitive explanation.

Perhaps cite some known phenomena or electrical principles (so far you've mentioned Thevenin where good old Ohm's law would have sufficed - you don't need a Thevenin equivalent circuit to add parallel complex impedances or at least you didn't when I went to school back in '93). Maybe put forth some measured data or name some specific geometries or talk about which geometry is GOOD for lowering inductance. Maybe mention ONE SINGLE ORDER OF MAGNITUDE for just a few "electrical attributes" instead of repeating the word "desireable" all the time. Maybe tell us *why* a stock cords inductance is unacceptably high for most audio circuits.

If juggling and playing is the best you can describe the mathmatics and methodology for implementing RFI suppression in AC cable design, then maybe you could have your "guru" post here. I am afraid your version of his story is far to watered down to be of any value.

Oh, and "for the record", if you want to put me through some schooling, be my guest. I'll take your money. So long as the courses are being taught by actual professors and mathmeticians.

Cheers,
Presto
