Baluncore's latest activity
-
Baluncore replied to the thread I Mechanism of Energy Conservation in Zero-Amplitude Sum of EM Waveforms.Where two phasors or vectors cancel, the result is not zero, it is just vanishingly small. Any phase or amplitude noise present, will... -
Baluncore replied to the thread B Water Wicking between two containers.Welcome to PF. You are fighting an uphill battle. If the wick at the top is in the water, water will flow from the high to the low...
-
Baluncore replied to the thread Ground loop on electronic audio systems.This was not a true hum loop, but was a more worrying situation. I noticed a "hot to the touch" power cable on a newly installed faulty...

Somebody, explain the joke to me.
-
Baluncore replied to the thread Earth ground resistance measurement.No, it does not. So there are two unspecified terminals. The terms 'former' and 'later', required that you earlier identify the two in...
-
Baluncore replied to the thread Beauty of old electrical and measuring things, etc..The 12AX7 continues to be used in guitar amplifiers today. I don't know why they worry you, it is just a matched pair of N-channel FETs...
-
Baluncore replied to the thread Defining Analog Computer Power.The bandwidth of a computational feedback loop, and the settling time of a digital to analog converter are relevant concepts.
-
Baluncore replied to the thread Earth ground resistance measurement."Semi-spherical"? No good can come from a word that is a misbegotten hybrid of two languages, Latin and Greek. Semicircle and hemisphere...
-
Baluncore replied to the thread Earth ground resistance measurement.Confusion arises in the first diagram, where equipotential lines cross the deep conductive electrode. To measure ground resistance...
-
Baluncore replied to the thread B Ultrasonic wave and regular sound wave.Welcome to PF. In air, water, or in solids? All low-amplitude sound waves propagate at the same speed, independent of frequency. In a...
-
Baluncore replied to the thread Ground loop on electronic audio systems.Yes, you can, if you place values on all the components. Notice that there is actually no L1 in a coaxial cable. The transmission line...
-
Baluncore replied to the thread Ground loop on electronic audio systems.There should also be a capacitor between E1 and E2.
-
According to p.50 of Brent's original publication (it is available on archive.org): "practical tests show that this [would slow down]...
-
Baluncore replied to the thread Ground loop on electronic audio systems.When you replace the conductors with inductor symbols, you also connect capacitors between the chassis of all devices and of all grounds.
-
Baluncore replied to the thread Ground loop on electronic audio systems.There is no such thing as zero impedance, or a vanishing voltage. A conductor will always have some inductance, and there will always be...
