"Linear", in circuit terms, means that you get the same output from a circuit every time you put the corresponding input into the circuit.
It's not nearly as mystical as folks like to make it sound. A lot of the language around it dresses it up to appear more than it is in an effort to be rigorous.
- freemint 5y agoCapacitors are linear but stateful, so would be memristors. I am not sure you characterization is correct.
- pkaye 5y agoA linear circuit is one which obeys the superposition principle. Its easer to analyze under frequency domain for example. https://en.wikipedia.org/wiki/Linear_circuit https://en.wikipedia.org/wiki/Linear_circuit
- capn_duck 5y agoThat's just not true. Its a very specific relation between the output and the input of a system.
- exmadscientist 5y agoAs other comments note, this is not the definition of a linear system. However, it is the definition of a time-invariant system, which is probably why it's coming to mind here. Systems that are both linear and time-invariant, sometimes abbreviated to LTI systems, are the most common sort of thing (i.e., model) that one actually analyzes. When time-dependence is present, it is always modelled explicitly and usually modelled as a complication of a time-invariant system.
- ur-whale 5y ago>means that you get the same output from a circuit Not sure where you were taught that, but it does not strike me as the generally accepted meaning of the term "linear". Where I hail from, linear means: f(a*x + b*y) = a*f(x) + b*f(y) aka the superposition principle.
