DaveE reacted to berkeman's post in the thread Design example for commercial high speed pcb with
Like.
I believe that @Baluncore and I have both said that this is a bad practice, so there are probably very few examples of it. You really... -
DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.This is a strawman argument. Simulators never represent "real" systems (chaotic or not) with perfect accuracy. Engineers never create...

DaveE reacted to Filip Larsen's post in the thread Undergrad Chua's oscillator circuit -- Intuitive picture with Like.
It seems you still are hooked up on the idea that the precise trajectory for a chaotic system is "the way" to predict its dynamical...

DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.For this sort of chaotic oscillator I don't think the ICs (or the Butterflies) matter much. Run the simulation longer and it will access...

DaveE reacted to Baluncore's post in the thread Undergrad Chua's oscillator circuit -- Intuitive picture with Like.
Initial conditions ".IC V(C2) 0.80000" produces a different outcome to ".IC V(C2) 0.80001". The differences are initially small, but...

DaveE replied to the thread High School Why would sailboat racers prefer a full keel over a fin keel?.OK, It's not a great sailboat, and it's not a great power boat. But it is suitable for it's purpose. Jack of all trades, master of none...

DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.I'm not sure what you mean by "a spike", the circuit oscillates chaotically, so everything is changing. But, generally, you won't get a...

DaveE reacted to Swamp Thing's post in the thread Undergrad Chua's oscillator circuit -- Intuitive picture with Like.
Re. the discussion about 'reality' of this simulation. If I understand correctly, the beauty of this class of systems is that it is very...

DaveE reacted to Baluncore's post in the thread Undergrad Chua's oscillator circuit -- Intuitive picture with Like.
That simulations are real simulations, is a truism. Simulators do not model reality, they model a conveniently reductive, idealised...
-
DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.Simulations can be very valuable when used appropriately. That's the problem; people think it's an easy answer to every circuit...

DaveE replied to the thread Undergrad Chua's oscillator circuit -- Intuitive picture.In the ideal circuit model: The only element that can dissipate energy is the resistor. The negative resistor (Chua diode) can only...

Here is a simulation in LTspice using real electronic components.

DaveE replied to the thread Undergrad Capacitor Voltages at t = 0: Zero or Split?.If y'all think repeating your position over and over, and over and over, and... will convince the other guy, you may want to focus a bit...

DaveE reacted to Dale's post in the thread Undergrad Capacitor Voltages at t = 0: Zero or Split? with Like.
As we have already discussed, the question is about ##t=0##, not ##t=0^+##. This is simply factually untrue. As the OP already discussed...
