cianfa72 replied to the thread Ground loop on electronic audio systems.Added capacitor C3. Now from this schematic, one should be able to analyze the impact of ground loop on the single-ended transmission... -

cianfa72 replied to the thread Ground loop on electronic audio systems.With reference to the diagram in the OP, I came with the following schematic L1, L2, L3 and L4 coils account for the inductance of the...

-
cianfa72 replied to the thread Ground loop on electronic audio systems.Yes, of course. That was just a theoretical assumption just to understand things... Sorry, if you were to draw a diagram, where would...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.By the way, w.r.t. the diagram in the OP, suppose the coax cable's external shield between C1 and C2 equipments had zero resistance...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Ok. You mean the PE wire/cable could be disconnected from the local earthing system or could have high resistance w.r.t. local...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Just to be sure: PE is just the wire/cable that is supposed to be connected to the Neutral wire (N) and/or to the local/domestic...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.Sorry, can you kindly help me in understanding such a scheme ? As far as I can tell, both coil windings do not make/implement actually a...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.No, at the moment no. If I were to draw a schematic, does it means it should be some sort of "Thevenin equivalent" driving the PE...
-
cianfa72 replied to the thread Ground loop on electronic audio systems.To be more precise, I should also include in the picture variable EM fields due e.g. to transformers within C1 and C2 chassis/enclosures...

Hello, I'd like to discuss what is called "ground loop". Consider the following scenario and call the set "C1 + S + C2" as "the system"...

cianfa72 replied to the thread I Invariance of 4-velocity.Yes, I have no idea why so many confusing definitions are used :rolleyes:
-
A scalar is a function on the base manifold. A vector is a member of the tangent space of spacetime. A traceless symmetric tensor is a...
-
Yes it will have an effect (unless you correct for it). A trivial 2d example would be choosing to measure distances in one dimension in...

cianfa72 reacted to Ibix's post in the thread B Does the gravitational distortion of mass still exist in the past? with
Like.
Ah - so (dropping a dimension for ease of visualisation) you (and @Dale) think the OP's mental model is that spacetime is a 3d block... -
cianfa72 reacted to PeroK's post in the thread B Does the gravitational distortion of mass still exist in the past? with Like.
That's a complete description of the spacetime geometry - hence, a complete description of gravitation in this case. You must add, of...
