When I visited Canada we passed houses on the outskirts of a city and the lady guide told us how much their value had increased in just a few decades. Most people wouldn't be able to now afford one.
Don’t know the stat for one, but concentration of wealth is everywhere. So looked it up, figures Canada not as concentrated or as exuberant total wealth. 1600 families 5.7% of wealth so mini mega wealth, 3.6 million top families own 8.7 trillion, so small fries compared Somewhat
walton familly as an ex 150 billion. Canada Thomson’s 8 billion. Also usa had 90 year head start on Canada.
Sup everyone. Thought I would check in. I'm in super cold Iowa today for work. Hammering down those computer viruses. The temp is a mind numbing -22. Burrrrrr. It's the coldest I've ever felt and I've been in a lot of cold places with lower temps.
Hope everyone is doing well. Hang in there with these cold storms coming through the US.
I've got a question about the wiring of a Balanced Input Attenuator (Volume Control) -
.
A single-ended attenuator connects between the input signal and GND, with the wiper providing the moveable tap that goes to the next stage.
.
A balanced output doesn't use a GND reference, since the signals are "floating" (+) and (-).
So, I'm wondering, when the (+) and (-) signals get connected to the "top" of the two attenuators - what gets connected to the "bottom" of them?
On this web page [ https://www.electronics-tutorials.ws/attenuators/attenuator.html ] there's a reference to the two balanced signals going to a center "GND", which should not be a signal GND, but could be a virtual ground, by connecting the two attenuators to each other.
.
Bad ASCII art example:
x (+) Signal Input
\
/
<- (+) Signal Output (Attenuator 1 wiper)
\
/
x Virtual Ground
\
/
<- (-) Signal Output (Attenuator 2 wiper)
\
/
x (-) Signal Input
You have to imagine that when turning the Volume Down, the Attenuator 1 wiper is rotating down, and the Attenuator 2 wiper is rotating up. As they get closer to each other, the (+) and (-) Outputs that feed the next stage differential inputs, gets smaller and smaller.
