| Aug 9, 2017 at 17:37 | comment | added | Fat32 | @Jazzmaniac I remember we had a discussion of this before :-) Form the question itself, as you said, yes all of them can be an eigenfunction of an (some) LTI system. But I belive they wanted to say which of them can be eigenvalues of arbitrary (therefore of every) LTI systems in general... | |
| Aug 9, 2017 at 17:05 | comment | added | Jazzmaniac | If the question was "which function is always an eigenfunction of an LTI system", then (c) would be the only correct answer. With the current formulation "which of the following can be the eigen signal of an LTI system", all answers are correct because each is an eigenfunction of the trivial identity system for example. | |
