Should the causal property be included here?
Not all linear systems are causal. Not all causal systems are linear. —Preceding unsigned comment added by CSears ( talk • contribs) 23:14, 21 September 2007 (UTC)
The article says a linear system "can be described" by a linear operator H that maps x(t) to y(t). But the article doesn't say HOW the linear operator H is used to describe the system, and it doesn't say what x(t) represents or what y(t) represents (other than calling them the "input" and the "output" which is uninformative). Does x(t) represent the state of the system? Does y(t) represent the state of the system? How do I find x(t+1) given x(t)? The rest of the article never even mentions H again.
AT MINIMUM the article needs a physical example of a linear system using the same notation H, x(t), and y(t). Halberdo ( talk) 04:34, 1 December 2012 (UTC)
This was recently posted to my talk page. I would appreciate some help from other editors in resolving this. ~ KvnG 13:45, 12 May 2014 (UTC)
"Linear system" has a wide usage in mathematics and does not specify this particular application, The usual term is "linear systems analysis" or a little more precisely, "linear systems-analysis". JFB80 ( talk) 15:37, 24 January 2016 (UTC)
I couldn't find any info about incrementally linear systems. Just an idea for expanding the article. Dalba 11:59, 2 January 2019 (UTC)
